ARCHITECTURE AND URBAN DEVELOPMENT. RESTRUCTURING AND RESTORATION

STATUS, PROBLEMS AND PROJECTS FOR DEVELOPMENT OF DISTRICT, URBAN PLANNING AND ARCHITECTURE IN BULGARIA IN EARLY 21ST CENTURY (AGAINST THE BACKGROUND OF THE MARKET ECONOMY AND THE UPCOMING FINANCIAL AND ECONOMIC CRISIS) PART 2

Part 2 of the article has a brief overview of the real estate market in Bulgaria and projections
concerning future investments into urban development projects. The author considers design and
development of business centres, business parks, multi-purpose centres, high-rise buildings and
residential housing. In 2000 - late 2008, the pace of construction was very fast, and it caused
negative compromises in the construction industry. Due to the hotel boom, the Black Sea coast now
accommodates numerous high-density hotel buildings. At the same time, residential housing build
in the early 20th century needs urgent restructuring. The construction sector experiences enormous
pressure, as major projects initiated in 2007 and 2008 are now suspended as a consequence of the
fi nancial crisis. The author believes that recovery actions shall include tax holidays for purchasers of
fl ats, extended loan reimbursement periods, and reduction of state and municipal tax rates payable
by construction companies.

The authors consider problems of optimum height (or length) of light wells in multi-storey
industrial buildings in the hot and sunny climate of southeast China. The researches were based
on the multi-component data analysis that included the analysis of dimensions of light wells in plan
view, analysis of natural light that they delivered and the time period of the use of the artificial light in
the workrooms of the above industrial buildings. Conclusions were made concerning the efficiency
of light wells in the upper and pre-upper storeys of similar industrial buildings.
Particular attention must be driven to the quality of the internal microclimate, which accrues
importance in the extreme weather conditions like hot and sunny climates. In the course of multiple
years, the problem of development and maintenance of the favourable indoor environment has
been the subject of research performed by the leading experts in building physics. The researches
concerning hot climates are mainly based on the research of the lighting, thermal and insulation
conditions in the said premises and development of architectural and structural concepts and solutions
aimed to improve these conditions.

The authors provide solutions to the relevant issue of development and construction of
foundations resting on a sliding layer as a method of external seismic protection of buildings and
structures. The authors have developed a system of automated operating control over the external
seismic protection of buildings (structures) that represents an automatic switch of the emergencylevel
seismic load. The authors have filed an application for the registration of their invention. The
proposed solution has everything in place to be widely applied to improve the seismic protection of
buildings and structures, especially those resting on problematic soils.
The authors provide their description of a paradox of foundations: foundations are analyzed
in terms of "upside-down" loads, whereas seismic loads have an opposite direction. The authors
provide their solutions to this problem.
The authors argue that methods of seismic protection incorporated into effective regulations
are limited, and they do not constitute any external seismic protection methods, whereas the
application of seismic isolation inside buildings is unreasonable, as it is limited by the requirement
to install it "above the foundation". Presently, the above methods are being reworked into foundation
platforms resting on a sliding layer. Their efficiency has been proven by a computerized model and
a theoretical analysis.
The authors also provide their argumentation in favour of the conclusion that relevant seismic
protection development trends are to incorporate advanced structural solutions, including methods
of external seismic protection.

The authors provide data on the influence of a round cap installed in the upper compressed
zone of soil onto displacement of laterally loaded single-pile supports identified on the basis of the
analytical method that they have developed. The authors demonstrate that both the front surface of
the round cap and its bottom contribute to formation of the supplementary resistance to displacements
of a laterally loaded pile due to (i) the friction force that arises alongside its contact with soil
in the event of a lateral displacement, and (ii) a vertical pressure under the impact of a moment load
in the event of a tilted slab. A round cap in the upper displaced zone of soil may cause a substantial
reduction (4-8-fold) of displacements of a laterally loaded pile if compared to the pile that has no
round cap.

The authors analyze rheological equations of viscoplastic landslides under natural conditions
and in the presence of a sparse row of piles as an anti-slide barrier.
Rheology of viscoplastic slides in the presence of buttresses that significantly alter the pattern
and speed of their motion has enjoyed little attention of researchers, although it plays an important
role in the analysis of stabilization of landslide flows. Elements of tensor calculus are used to analyze
the motion of the viscoplastic matter. An exact solution to the problem of gravitational motion
alongside an inclined plane was used as the main one. It is proven that the motion pattern of the
viscoplastic matter contains rigid zones where the flow velocity is equal to zero.
In the event of motion of a layer alongside an inclined surface, the rigid zone moves together
with the viscous surface, and the overall velocity of the viscoplastic flow will be determined by the
rheology of the viscous surface.
This paper provides solutions designated for the identification of rigid zones of cohesive soils,
as well as soils that demonstrate internal friction and cohesion.
The authors have proven that whenever piles are used, the nucleus of the landslide mass is
stabilized.

Plates are widely used as flat structural elements in various spheres of construction and engineering.
Development of industrial and residential building techniques furthers development of
the construction science. Therefore, the design and the refined theory of plate vibrations is one
of signifi cant issues considered within the framework of the applied theory of elasticity, which is of
practical interest to the researchers. The authors provide a summary of frequency equations that
describe self-excited oscillations of a transversally isotropic plate resting on the strain foundation
bed, if one edge of the plate is flexibly fixed and the other three edges are hinged. Oscillations are
described by partial differential equations of the fourth order. The problem is resolved through the
employment of an approximate method of decompositions. As a result, the frequency equation is
derived to identify self-excited lateral oscillations of the plate. The equations derived by the authors
for the purpose of identifi cation of the frequencies of self-excited transverse vibrations of a plate are
fit for practical use, and they may be applied in calculations to identify the dependence of the selfexcited
frequency of the plate on its geometry.

The authors present their methods of experimental determination of parameters of statically
indeterminate pre-stressed reinforced concrete bar systems in the out-of-limit state. The authors
also present their method of the out-of-limit state modeling and experimental determination of dynamic
strain and stress values typical for such systems in the event of the abrupt failure of one
system element.
Methods of experimental determination of parameters and dynamic loadings typical for deformations
caused by the abrupt failure of one of connecting elements drive special attention to
the analysis of deformations and cracking of pre-stressed structures on the basis of the research
of the nature of destructions and redistribution of dynamic forces within the above elements. The
following parameters have been identified in the course of tests: longitudinal strain of compressed
and cracked concrete elements; strain-stretched connecting pieces (calibrated covers); defl ections
of beams, including the application of loads beyond design parameters; load intensity and nature
of cracks and crack openings before and after the application of loads beyond design parameters;
overall patterns of destructions and prototypes of destructions caused by a sudden fracture of a
welded connecting element; increments of displacements and oscillations of pre-stressed elements
of beams after a sudden destruction of a connection under pressure.
Experimental parameters are needed to draw the curves of diagrams of experimental static
and dynamic deformations necessary for the survivability analysis.

The nature of the stress-strain state of membrane structures is highly dependent on the initial
strain. The article contains an analysis of the folding pattern under the weight of the cover, depending
on the number and location of internal supports. The authors have analyzed the two alternative
layouts of supports. In the first case, the option of one (central) support is considered; in the second
case, the cover is based on vertical load-bearing structures located in four points at equal distances
from the ends of the block.
Numerical calculations performed by Lyra 9.4 software have identified that the biggest deflection
of the membrane occurs in its central part.
We can conclude that the most intensive folding originates from the edges of support struts.
A qualitative assessment of the results of numerical calculations was performed using the testing
model of the membrane cover. Conclusions about the distribution of initial strains over the structure
and assessment of their influence on the stress-strain state of the membrane unit were made.
A qualitative picture of the deformation was obtained using the numerical simulation and its comparison
with the experimental results.

A light steel thin-walled structure is very effective. The durability and strength of structures,
investment efficiency, high construction intensity, excellent technical and operational characteristics,
backed by extensive architectural solutions make the employment of the technology of light
steel thin-walled structures particularly efficient in low-rise commercial construction. Light steel thinwalled
structures represent a relatively new area, therefore, the regulatory base required for a reliable
analysis of these st ructures is unavailable, and this fact limits their use in construction. Russia
has no special norms regulating the above parameters. The underdeveloped regulatory framework
in Russia gives rise to the problem of market saturation with cheap low-quality fasteners.
The purpose of testing is to determine the mechanical properties of steel . The tests were applied
to five separate self-tapping screw connections. The purpose of testing was also to determine
the bearing capacity and the stress-strain state of connections.
Numerical calculations using the finite element method required a steel diagram. MGSU specialists
mad e tensile test specimen to determine the physical and mechanical properties of coldformed
thin-walled steel profiles at the "Sector for Testing of Building Structures". Identification of
pliability of connections was required to employ the dependence obtained using numerical calculations
of structures. As a result of the work performed at MGSU, a diagram of thin-walled cold-formed
steel profiles was generated.

The objective of the research is to analyze the stresses experienced by radiation and heat
screens similar to those installed at nuclear power plants. This type of design, also known as "the
dry protection" is designated to reduce the effects of radiation and heat emitted by the reactor.
The authors have considered the axis-symmetric problem resolved through the employment
of the variational difference method. The solution to the problem is composed of several steps. The
first step represents the distribution of the temperature field over the thickness of the screen. The
second step represents the distribution of the neutron flux in the thick screen. The third stage represents
the change in the Young's modulus due to thermal and radiation effects. The fourth stage is
the immediate determination of stresses in the thick screen.
The authors have proven that the combined effect of radiation and thermal stresses produced
on the Young's modulus causes substantial voltage change in the thickness of the cylinder, whereas
the solution that assumes a constant value of the Young's modulus is less accurate. The aforementioned
phenomenon suggests that no changes in physical and mechanical properties of materials
can be neglected, whenever structures exposed to several supplementary (temperature, radiation
exposure, etc.) loads are analyzed.

and the transfer ratio. Identification of accelerations is important due to potential negative influence
of vibration on adjacent structures. Vibration protection patterns analyzed in the article represent
a SDOF system, a scheme that has an additional inertial block and a system with a Passive
Tuned Mass Damper (PTMD). The author considers vertical oscillations of systems that have one
and two degrees of freedom by taking account of transient modes of operation of items of machinery
inducing harmonic loads (modes of activation and stopping). The two methods are employed,
including the method of normalized eigenforms and the method of transfer and impulse response
functions. The method of normalized eigenforms relies on transforming the mass displacement vector
into a linear combination of eigenforms. Solutions are obtained by applying the Duhamel integral.
The method of transfer and impulse response functions is based on a correlation between these
functions. This method proves to be efficient in respect of less than 3 DOF systems, and it doesn't
require any identification of eigenforms.
The PTMD system has proved to be particularly efficient if applied to the items of machinery
inducing harmonic loads (the fan), as the damper is tuned to the operational frequency of the
machines. The system that has an additional inertial block is mostly efficient if applied to items of
machinery inducing impulsive loads (the sledge hammer) due to smaller dynamic loads transmitted
to the foundation.

USING LOGIC IN PRACTICAL SUBSTANTIATION OF STABILITY OF BUILDING FOUNDATIONS: OVERVIEW OF A LITTLE-KNOWN WORK WRITTEN BY N.M. GERSEVANOV

The author analyzes the findings made by N. Gersevanov, founder of the Russian school of
soil mechanics, covered in one of his little-known works. His method of solving problems of logic
within the framework of structural mechanics boasts a backstory. N. Gersevanov employed a quote
of Galileo Galilei who had employed the "reductio ad absurdum" type of deduction to refute the
Aristotle's proposition concerning the dependence between the rate of fall of bodies and their mass.
The author argues that this work written by N. Gersevanov was the first attempt to apply the
logic in the area of civil engineering technology; this attempt anticipated further efforts and research
undertakings implemented by V. Shestakov, developer of the relay logic. N. Gersevanov employed
the language of symbols developed by Louis Couture and entered the symbols of identity, logical
addition and multiplication into the logic formulas designated for the identification of stability of port
structures. Further, N. Gersevanov switched from formulas to arguments, and he employed both
direct and indirect argumentation to refute the statement that read as "the building was unstable".

The authors cover the problems of the numerical analysis of corrugated web beams exposed
to constrained torsion. The calculation is performed using the finite element method. Virtual solid
models and software package "Lira" are employed to perform the structural analysis. The results
of the comparative analysis of performance of beams that have flat and corrugated webs and that
are exposed to constrained torsion are presented in the article. Corrugated web beams that have
different geometrical shapes of corrugations are considered.
The results of the research have proven that a beam that has a corrugated web demonstrates
average deflections of 15-18 %. The rotation angle of the midsection of a corrugated web beam
is by far below the one of similar beams that have a flat web. Comparison of beams that have different
corrugation web patterns and that are exposed to constrained torsion proves that beams that
have a corrugated triangular shape web have a better bending stiffness, while beams that have
a trapezoidal shape demonstrate the best torsion stiffness, given that the geometric parameters
remain the same.
The authors believe that the flexural stiffness of beams with a corrugated web needs more
research, depending on its geometric characteristics. These results can be taken as the basis for
the empirical and analytical dependence on the definition of deflection. Due to the fact that beams
with a corrugated web are less sensitive to the increase in the eccentricity of load, it makes sense to
apply the method of calculation of a flat web beam exposed to constrained torsion, but the qualifying
factor is to be applied.

In the paper, the researchers have estimated the influence of pre-stressing of reinforced concrete
elements upon the dynamic loading parameters in the event of beyond-design actions.
In particular, the case of reinforcement of a crossbar, if considered absent of any pre-stressing,
is considered in the paper. The authors have proven that the presence of brittle fracture elements
leads to decay in time-driven vibrations of rods within the statically indeterminate structural system.
The findings have been made on the basis of the magnitude of specific efforts (the bending moment)
and the corresponding strain. Besides, the authors have formulated the condition of permanence of
the total per-unit energy of structural elements. The influence of the above-mentioned parameters
on the design safety of a system is identified.

STRUCTURAL RELIABILITY IN EUROCODES

The structural reliability recommended in Eurocodes and other international documents vary
within a broad range, while the reference to the failure consequences and design working life is
mentioned only very vaguely. In some cases the target reliability indexes are indicated for one or
two reference periods (in Eurocodes for 1 year and 50 years), however no explicit link to the design
working life is usually provided. This article attempts to clarify the relationship between the target
reliability levels, failure consequences, the design working life and the discount rate. The theoretical
study based on probabilistic optimization is supplemented by recommendations useful for code
makers and required by practicing engineers. It appears that the optimum reliability indices depend
primarily on the ratio of the cost of structural failure to the cost per unit of structural parameter, and
less significantly on the design working life and on the discount rate.

In the course of construction and restructuring of unique buildings and structures, any architect
faces the need to design complex surfaces that have curvilinear geometrical forms that cannot be
neglected. In turn, designs with complex curvilinear geometrical forms require higher skills in their
development, as the complexity of their design and implementation is a lot higher than that of elements
that have flat surfaces.
The value of plaster cannot be underestimated. Plaster applied to surfaces of various buildings
and structures (walls, partitions, columns) flattens the surface, shapes it up and protects it from
moisture and fire; it improves resistance to heat transfer; it reduces air permeability and improves
the soundproofi ng properties of protected designs, etc.
All pre-set parameters of plaster are to constitute the subject of random inspections, and inspection
results are to be considered in the course of acceptance of any work. The most important
though hard to control parameters of plaster include:
bond strength, thickness, moisture content and density;
flatness or its radius of curvature;
deformation properties of the plaster layer versus deformation properties of the design.
Control over compliance with the design is hard to implement as curvilinear surfaces are located
at a significant height above the ground and/or the floor level. Therefore, there is a need to develop a
non-destructive method of quality assurance of construction, restructuring and finishing works.
The solution to the problem becomes possible due to development of specific hardware and
software designated for remote though accurate identification of the surface curvature.
The authors have developed a modified range-oriented laser methodology that employs angular
segments to remotely assess the flatness of the building structure and its radius of curvature and
to determine the deviation of its value from the designed one. The software also makes it possible
to implement the quality control of the work performed over the curved surfaces coated with various
types of plaster.
The proposed solutions have been pilot tested in practice, and they are ready for use in the
building industry, namely, in construction, repair and restructuring works.

The method of identification of the water vapour permeability resistance of finishing layers of
composite thermal insulation facade systems that have thin external plaster layers was developed
by the authors. The above systems comprise one layer of the heat insulation material that has a 5
mm finishing coating. This system is fastened to the building wall. The method is based on the results
of an experiment held to identify the resistance of all systems to the water vapour permeability
irrespective of the availability of finishing layers.
The proposed method is more accurate than any of the previously known methods that contemplate
the experimental determination of coefficients of water vapour permeability of materials
of finishing layers and subsequent calculation of the overall resistance to the water vapour. The
State Standard «Method of Determination of Resistance to the Water Vapour Permeability» that
implements the «wet cup» technology has been applied. The method has been employed to identify
the resistance of finishing layers of BAUMIT insulation system to the water vapour permeability.
BAUMIT has a thermal insulation layer made of mineral cotton. It has been identified that the overall
resistance of the finishing layer to the water vapour permeability, as determined in accordance with
the methodology developed by the authors, is twice as less efficient than the overall resistance
identified in accordance with prior methodologies. This difference in the characteristics of finishing
layers essentially raises the accuracy of projections of the moisture behaviour of all composite facade
insulation systems that have thin external plaster layers.

Results of examination of the structure formation process undergoing in the system composed
of sodium hydrosilicates and barium chloride are presented in the paper. It is proven that the process
of initial structure formation comprises two stages. During the first stage, the primary frame
structure of barium hydrosilicates is formed. It is followed by the process of restructuring accompanied
by the dissolution of the silica acid and formation of barium hydrosilicates. Later, hydrosilicates
consolidate and reinforce the material.
Results of optical examinations are confirmed by the study of the rheological characteristics
of the mixture. Methodology of identification of the moment of initiation and completion of the hardening
process together with duration of primary and secondary frame formation is developed on
the basis of theoretical rheological curves. Time intervals of initial structurization are revealed for
the system comprising sodium hydrosilicates and a modified curing agent in the event of different
amounts of admixtures. Time intervals and average rates of structurization are also identified for
each stage of the process.

Relevance of traditional replacement of scarce resources of the construction industry similar
to waste products in terms of their composition and condition is unquestionable from the viewpoint
of their economy and the environment. The structure and physical properties of cement concretes
filled with slag waste products are determined by the type and number of tumours, the phase generation
rate, and the structure of the porous space. The research findings have proven that cement
concrete compositions that contain slag demonstrate higher strength than those that have no slag.
Slag waste products can be used as concrete aggregates.
The hydration ratio of samples of cement that had slag waste products added and the hydration
ratio in the course of the composition formation were identified using methods of microscopy
analysis. The structure of samples that had slag products added was analyzed through the employment
of stereoscopic microscope MBS-9 (3.3 - 100.8X) capable of producing a direct-viewing
image of the sample. The point method was employed to analyze the slag phase quantity. The
point method of quantitative metallography was employed to identify the volume ratio of structural
components or phases. Practical implementation of the point method requires a magnifi cation rate
sufficient for the structural components to be big enough to identify whether the point falls within the
phase section or not. The point-to-point distance is to prevent two or more point to fall within one
section of the micro-particle under research.
Optimal mineral additive quantity based on the minimal cement consumption rate or the minimal
cost of concrete, and optimal mineral additive quantity based on the structure determined by the
physical condition of the system, are driven by the redistribution of particles over the cement grout.
The optimal mineral additive quantity from the viewpoint of its structure is the one to be selected, as
the concretes that demonstrate the structure of this type have maximal strength as a response of the
"Cement + Modifying Additive System" to the optimization of the disperse medium of the concrete.

In the article, the authors substantiate the employment of the rheological method of identifi cation of the thickness of the bitumen layer formed on the surface of the mineral component. The
analysis of existing methodologies of assessment of the physical and chemical activity of mineral
components in relation to the bitumen has proven the unavailability of any universal methodology to
substantiate the use of mineral fillers to be added to the asphalt concrete. The authors have demonstrated
that identification of thickness considered as a kinetic and an adsorption layer requires
the employment of nothing else but the bitumen. Viscosity measurements of disperse systems composed
of bitumen and mineral components are to be taken at different temperatures.
The filling range of the above systems satisfying the Einstein equation (under 5% by volume)
has also been identified. The nature of dependence between the viscosity fluctuation pattern of the
disperse systems composed of bitumen and the mineral filler, on the one hand, and the degree of filling
and the temperature, on the other hand, has been identified. The nature of dependence between
the viscosity fluctuation of bitumen and the castor oil and their temperature has been identified, as
well. The authors have also calculated the temperature at which the viscosity of bitumen reaches its
minimum value (T = 220 °C). The authors have demonstrated that the mineral components under
research produce only a kinetic layer that turns thinner as the temperature goes up, whereas no
adsorption layer can be identified experimentally through the employment of the rheological method.
Comparison of the data obtained by the authors with the theoretical findings demonstrates
their sufficient convergence, reliable repeatability of the proposed method of identification of thickness
of the structured bitumen, and physical and chemical activity of the mineral component. The
data presented herein have also proven the inexpediency of application of the methodology of
identifi cation of adhesion between bitumen and the mineral filler according to State Standard GOST
11508-74*.

The authors have analyzed types of cohesion between water and fillers that demonstrate
varied granulation. The authors have proven the influence of the moisture content in fillers onto their
packing density.
An experimental and theoretical analysis of influence of types of cohesion between the water
and surface particles of the liquid phase in the period of initial structurization of foam-concrete
composites represents an intermediate step on the way to identification of patterns of formation of
structures that have perfect physical and mechanical properties.
The experimental research consists in the moisture treatment of disperse granular particles
of sand and dense limestone of different fractions. The experimental research has proven that the
packed density of dry fillers depends on the size of elementary particles; therefore, the packed
density depends not only on the type of packing of particles, but also on correlations between their
gravitational and surface energy.
The amount of water consumed in the course of formation of adsorption films has turned out
to be proportionate to the per-unit surface of granular particles. The moment when the particle surface
was filled with the adsorption moisture was registered based on the minimal average density
in cases of the varied moisture content in the materials under research. Each granular composition
demonstrated higher parameters of average density upon formation of the adsorption layer of moisture
due to the presence of the film characterized by higher density.
The growth of average density in the absence of any water loss proves that the granular system
has a film moisture content that demonstrates the properties of a solid phase.
The findings have proven that the degree of dispersion of granular particles regulates the film
moisture content in the composites designated for the production of foam-concretes. The above
property ensures production of composites that have a high workability and a stable aggregative
state.

The authors consider the problem of maintenance of buildings and structures of architectural
merit. Expedient resolution of this problem consists in the application of a mineral hydraulic binder
that has a particularly fine, gradually and smoothly changing granulometric composition and explicit
and steady chemical and mineral composition. The above binder is recovered as a result of
the air separation of Portland cement. The above binder comprises Portland clinker, furnace slag,
and regulator of hardening and mineral additives of R-X, R-U, and R-F brands. The authors have
also analyzed the characteristics of several brands and their physical and mechanical properties.
Injection-based stabilization of soils and structures is performed through the application of finely
dispersed binders used as water suspensions. The choice of binder brands applicable to concrete
and masonry structures that have damages of different nature is based on their granulometric composition.
The authors have proven that injections of suspensions are to be made at a low pressure
with a view to the filling of the porous space of the medium. The practical data obtained by the authors
has proven that impregnation of soils both improves their bearing capacity and converts them
into structural elements. Application of finely dispersed binders improves impervious properties of
strengthened massifs and their resistance to various aggressive actions, as well as their curing at
negative temperatures, rate of strength development, etc.

The objective of this research project is to substantiate the optimal values of disperse calcium
carbonate waste materials, to ensure their granulation into artificial stone, and to substantiate the
output rate efficiency.
In the course of the research, the authors assessed the lump-forming rate demonstrated by
calcium carbonate waste materials and cement grade CEM I 42,5 N on the basis of their molecular
and capillary moisture capacity. The assessment methodology that defines the threshold of the
lump-forming capacity, as well as the coefficient of output of man-made gravel for different dispersions
of calcium carbonate waste materials have been identified. Data reliability is based on the
mapping of the nature of dependences between the coefficient of lump-forming and the coefficient
of gravel output on specific surface areas.
The authors have identified that calcium carbonate waste materials have a lump-forming factor
that is close or equal to 100%, if its dispersibility is equal to 400-600 m2/kg. In this case, the
highest lump-forming rate is accompanied by the waste fineness of 500 m2/kg.

Some peculiarities of dry friction that represent the outcomes of several well-known physical
phenomena but that are insufficiently accurately and simply explained in the scientific literature, are
analyzed in this paper. The authors research into the reasons for the oscillation of strings of bowed
string instruments in furtherance of the laws of mechanics; they also explain differences in the sound
produced by strings of bowed and plucked instruments; they study the reasons for the motor car skid
and provide their recommendations how to overcome it.
The recommendation to rotate the steering wheel in the direction of skidding rather than vice
versa as the one could expect from the viewpoint of common sense, gives rise to confusion and
even protest of drivers (mainly, the new ones) and drastic consequences. Let us once again emphasize
that this driving pattern refers to rear-wheel steering cars (so-called "classics"). As for frontwheel
drive cars, one can turn the steering wheel in the opposite direction of the skid without retarding
the throttle, but it is also advisable to release the brake of the front wheels and fulfill the braking
by the rear wheels only.

The subject of research is the steady pressure filtration of the unconfined groundwater in the
heterogeneous bed, if the product of the transparency coefficient and bed thickness is represented
as a square of an arbitrary harmonic function of coordinates of bed points. The study of the groundwater
filtration within a heterogeneous bed using the «transition method» is reduced to the search
for potential parallel-plane flows of the ideal incompressible fluid using the superposition of point
sources and multipoles of different order. Application of the «transition method» instead of a regular
integration of differential equations in the series is a simple and obvious method of generalizing the
well-known Dupuis formula to identify the well capacity within a homogeneous bed by extending it
to the whole variety of heterogeneous beds, if the product of the transparency coefficient and bed
thickness is represented as a square of an arbitrary harmonic function of coordinates of bed points.
The above sequence of operations produces a compact formula describing the pressure distribution
within a pressure bed, if the external boundary of the groundwater is circular.

An overview of water treatment technologies employed at the heat-and-power plants of
Astrakhan is made by the authors. Water treatment facilities are in a very poor condition. As a result,
heat-and-power equipment suffers from considerable scaling, fouling and corrosion problems. New
membrane technologies, including ultra-filtration and nano-filtration, seem to be a promising way to
improve the water quality. The evaluation of the present-day water treatment efficiency with account
for the effective standards and requirements makes it possible to conclude that new pressure-driven
membrane processes must be implemented at heat-and-power plants.
Membrane technologies will improve the quality of water processed at operating power generating
stations or the quality of the water supplied to new structures of the city of Astrakhan; they will
reduce the reagent consumption rate and improve the role of water purification systems as barriers
that prevent water contamination. Besides, membranes ensure a high efficiency of turbidity removal,
and membrane facilities are small and simple in operation. The main difference of membrane technologies
if compared to conventional sedimentation and filtration systems consists in the high quality
of water irrespective of fluctuations in the temperature and composition of inflowing flows of water.
Authors are going to continue their research into the issue of potential wide-scale introduction
of newly developed techniques at the heat-and-power plants of Astrakhan to provide clear water to
boiler plants at low operational costs. The research results indicate that the above approach has a
strong potential in terms of water treatment in the power industry. The new procedure was developed
by the authors to identify and project the scaling and fouling rates within membrane modules
and to predict the membrane performance (permeate flux) depending on the feed water quality and
modes of operation.

This paper addresses the biological treatment of wastewater associated with removal of nitrogen.
Results of laboratory experiments that involve nitrification and denitrification are also presented
and analyzed in the paper.
Discharges of inadequately treated and untreated wastewater have a negative impact on
the aquatic ecosystem. The biological treatment of the wastewater that includes denitrification is
strongly influenced by external factors. They need thorough research at the stage of design of water
treatment facilities.
The objective of this research is development of effective construction technologies on the
basis of experimental studies with a view to the modernization of biological wastewater treatment facilities.
The analysis of the latest scientific papers on water treatment demonstrates that the singlesludge
nitrification and denitrification technology is the most effective and the simplest one in terms
of its implementation.
The studies were conducted at the research laboratory of Moscow State University of Civil
Engineering. The laboratory facilities make it possible to perform the processes of nitrification, denitrifiation and sedimentation. The composition of the wastewater used in the experiment was close
to that of the natural wastewater.
Optimal process parameters of a wastewater treatment plant, including capacities of nitrification
and denitrification tanks and concentrations of nitrate required for effective biological removal
of phosphorus, were identified in the laboratory. Positive results were obtained in terms of removal
of organic compounds and nutrients. The technology of nitrogen removal from the wastewater was
developed. The proposed technology of modernization of biological wastewater treatment facilities
is based on conversion of existing aeration capacities into nitrification and denitrification zones, and
it does not include construction of any new premises.

The authors examine the applicability of the physicochemical theory of effective stresses to
sandy soils. It is proven that the above theory may be furthered by the argument that all three
types of energy contacts, including coagulatory, transient and phase contacts, are present in sandy
soils. Coagulatory contact predominates over the other three types of contact. The authors provide
their findings in terms of morphological peculiarities attributable to genetic differences of quaternary
sands. The authors have completed an experimental research to identify the fixed water content in
sands and artificial mixtures that have a sand grain size, and they have also analyzed dimensions
of the per-unit surface of samples of natural sands and their fractions to identify correlation between
morphological peculiarities of sands and their maximal molecular water-absorbing capacity. The
authors have proven the presence of a correlation between the morphology of sand grains and their
number in the test sample exposed to the research undertaking, as it determines the number of
contacts between particles of sand.
The experimental data has proven that the principal provisions of the physicochemical theory
of effective stresses are applicable to sandy soils. Natural sands that have particles of different
shapes and surface nature demonstrate different types of contacts that prevent compliance of analytical
data with the results of experimental researches. Moreover, natural dimensions of coagulatory
contact areas of "sandy" systems substantially exceed those identified analytically. Areas of per-unit
surfaces of sands that contain particles with highly developed surfaces and clay films exceed those
of rounded particles the surfaces of which are smooth and polished as a result of their soft friction
in the water. This phenomenon boosts the thickness of adsorbed hydrated or solvated shells. As the
influence of physicochemical factors onto effective stresses in sands is not as prominent as in clays,
supplementary and more accurate experiments are to be held in respect of separate sand fractions
of monogene sands and in respect of samples of natural sands.

The authors argue that optimization of monitoring systems is a complicated task, as multiple
factors need to be taken account of at one and the same time. The authors consider a monitoring
system as a system of "supervision" that incorporates a set of tools, as well as registration,
archiving, classification, and analysis of inspection results, inclusive of their comparison with the
projected data, development and implementation of engineering solutions.
The basic goal of any geomechanical monitoring project consists in development of a methodology
of rational arrangement of items of monitoring equipment that employ GIS technologies. The
objective of this research is to apply advanced numerical methods in combination with geographic
information systems with a view to the optimization of a system of monitoring applicable to subterranean
structures. Should the proven methodological and scientific validity of the research findings
be in place, long-term geomechanical projections of the structural behaviour will be feasible. The
proposed methodology may be introduced as a standard method of structural behaviour monitoring
in the course of construction and operation of structures for engineering solutions to be made in the
real-time mode. The principal goal of a monitoring system is the identification of the rock nature,
processes initiated in the medium, their development pattern, and the identification of technical and
economic factors of impact onto the engineering solutions to be made at each stage of engineering
surveys, design, construction and operation of major subterranean structures.
The analysis of calculations made for various loading scenarios have proven that any further
research should take account of a lateral load that is equal to doubled vertical loads.
The research was performed at a subterranean structure composed of two parallel chamber pits.
The analysis of GIS modeling methods has proven that development of GIS projects requires
the employment of statistical methods of the multidimensional analysis. Employment of multidimensional
analysis methods makes it possible to examine the geological features that demonstrate a
high degree of complexity. Terrain modeling requires the employment of models of formal characterization
and differentiation. Identification of positions of geological strata and tectonic dislocations
may be reduced to interpolation and extrapolation.
The model of a subterranean structure is implemented in the GIS and databases, and it incorporates
the data banks entitled "Rock", "Massif", "Structure and Massif", as well as the data banks.
that contain surveying, geological and supplementary information. The GIS also comprises a topographic
site plan, a geologic description of a massif (stratifi cation, lamination, as well as a complete
assessment of each major massif crack).
The subterranean structure of a radioactive waste storage site was the subject of a 3D numerical
experiment. Its results were entered into the GIS project database. Positions and lengths
of extensometers were optimized on the basis of the simulation performed in furtherance of the
methodology developed by the authors. Positions of extensometers were registered in the GIS as
reference points.

The author considers the general principles of self-organization of open economic systems of
construction enterprises as a strategic criterion of their progressive self-propagation and efficient
operation in the market of construction services.
Self-propagating systems demonstrate particular characteristics that make them similar to developing
objects of the real life. These characteristics are based on the presence of active elements
and have dual properties: they are the new systems useful for the overall system, but, at the same
time, they cause uncertainty and make the system difficult to control.
Mechanisms and characteristics of self-organization of open systems have been identified by
the author. It has been proven that the evolution, self-propagation and improvement of functional
abilities of economic systems depend on the cyclic absorption of three types of energy which is
equivalent to the information entropy.

An important problem in development of an integrated multi-functional system of video monitoring
and recognition of objects is the problem of an interface that would provide a link between
various programme applications of the system and between applications and users. This interface
must be configured with reference to the object that the system of video monitoring will be attached
to, and it must be based on data transmission channels, skills and competences of users.
The authors specify the basic requirements to the software and the user interface. The concept is
implemented as a self-software facility that has successfully passed a test in ergonomics and speed.
In this project, an attempt is made to develop and implement a user interface that assures the
best relationship between individual modules of an integrated system and between the system and
the user. Therefore, the interface is to meet the following requirements: flexibility, volatility, mobility,
and frequency of principal forms and templates.
Design and development of a user interface incorporates development of pattern dialogues,
resolution of user problems, WIMP (window, icon, menu, pointing device), applied graphic scenes,
as well as connection of the interface to the application. The characteristics of users are employed
as the criteria of the interface adaptability; they can be divided into the following semantic groups:
demographic indicators, individual psychological features, psychomotor qualities, cognitive abilities,
training and qualification, motivation, nature of the system interaction with software applications.
This approach assures a high productivity of user actions through improvement of ergonomics and
better performance of the interface.

The authors have completed a research project that consists in the study of scientific and
technological fundamentals of an innovative construction technology that incorporates elements
of Product Life Cycle Management (PLM-elements) applied to low-rise buildings. Unified Modeling
Language (UML) has been applied to describe domain models of the construction technology. The
concept of low-rise construction that has PLM elements is based on a common information netspace
and a unified information model of a construction facility, or a BIM model. The BIM model
is developed on the basis of the Autodesk platform using Revit Suite software. The processes of
Product Data Management support are operated by PLM/PDM system, such as Lotsia PDM Plus
software. The main conclusion has been made that the implementation of the above technology is
only possible for an industrial cluster of low-rise residential buildings. Development of the above
cluster is a separate theoretical and practical challenge.

The authors consider the problems that accompany development of construction conflict management
techniques using infographic modeling. The authors analyze comprehensive safety and
comfort assurance requirements applicable to an intelligent building. The authors provide a brief
overview of systems that comprise an intelligent building. The authors argue that there is a pressing
need for the study of the fundamentals of construction conflict management as a new theoretical
and applied discipline. An intelligent building as a constituent of the Man-Machinery-Environment
system capable of identifying impacts produced by the environment, of perceiving images and of
identifying them. Whatever the capabilities of an intelligent system, it cannot respond to any impacts
or disturbance produced by the external environment absent of any human involvement due to its
local nature. Therefore, innovative development of the technology of an intelligent building is accompanied
by innovative conflicts. A conflict facilitates the search for the optimal patterns of interaction
between the constituents of the Man-Technology-Environment system that operates within the
framework of the restriction that consists in the fact that aggregated parameters of impacts, control
over the status of the system and its intrinsic processes shall not cause its liquidation.

The authors consider a method of numerical assessment of the level of intelligence and automation
of buildings. This novel original method designated for the calculation of an abstract coefficient indicating the building intelligence and an abstract coefficient demonstrating the level of
building automation is proposed by the authors.
Engineering systems of buildings are analyzed within the framework of processes associated
with their functionality. These processes are subdivided into sets depending on their nature and degree
of control. The processes of one set are engaged in the building intelligence evaluation, while
the processes within the other set are involved in the evaluation of the building automation level.
Abstract coefficients of intelligence and automation are calculated on the basis of objective
quantitative characteristics of engineering systems, for example, BTU and meters. This approach
allows engineers to avoid any biasness in making their assessments.

The authors argue that irregular geometrical patterns of industrial premises and items of the
process machinery installed in industrial premises cause redistribution of the acoustic energy and
its essential acoustic properties, including the average free path length, the reverberation time, and
the average sound absorption coefficient. Any failure to take account of the above influence causes
errors in identification of the sound pressure intensity and in assessment of efficiency of design and
acoustics-related actions aimed at noise reduction that incorporate sound-proof facing.
The authors present the results of simulation of acoustic processes in the premises that have
items of process machinery installed, and analyze their influence on the sound absorption intensity.
The software developed on the basis of the beam tracing method is designated to assess the influence
of patterns of arrangement of items of equipment onto acoustic parameters of premises. The
software comprises independent modules designated for the simulation of acoustic processes in
different premises that demonstrate different acoustic properties. The results of the research demonstrate
that the software simulation of noise processes on the basis of the method of beam tracing
is an effective tool that may be effectively applied in the analysis of noise patterns inside industrial
premises. The software may be employed to identify integrated acoustic patterns inside industrial
premises with account for the influence of dimensions of premises, characteristics of items of process
machinery capable of disseminating sounds, etc. and other factors of signifi cance in terms of
the distribution of reflected sound energy. Presently, advanced software is being developed on the
basis of the proposed method of noise assessment in the premises that have irregular geometrical
patterns.

According to existing design standards, explosive loading represents a special type of loading.
Explosive loading is, in most cases, local in nature, although it can exceed the loads for which
buildings are designed by a dozen of times.
The analysis of terrorist attacks with explosives employed demonstrates that charges have
a great power and, consequently, a substantial shock wave pressure. Blast effects are predictable
with a certain probability. Therefore, we cannot discuss the no-failure operation of individual structures.
The estimated reliability of buildings is a more important problem. That's how we can save
lives of those people who are outside of the area impacted by an explosion.
Explosive loading is a variable random process influenced by a variety of factors, including the
charge geometry, weight, etc. A shock wave can be reflected from surfaces and objects. Reference
data concerning physical properties of models of explosives are provided in various sources. That's
why we can talk about the blast load value with some probability.
The article deals with the probability modeling of the shock wave pressure. The charge weight
is chosen as a random parameter that has a normal Gauss distribution.
Any structural design must be backed by reliable and verified calculations and mathematical
models based on advanced high-speed PCs and software. The finite element software package
ANSYS/LS-DYNA was employed to complete this research. The problem was solved in the time
domain through the employment of the fourth integration of equations of motion.
We can assess the reliability of structures and buildings if we know the parameters of random
explosive effects. Numerical simulation helps identify random explosive impacts. This problem is
relevant in connection with the construction of unique high-rise buildings and extensive sports facilities
that accommodate dozens of thousands of viewers.

Currently, continuous monitoring of the technical condition of structures is in most cases reduced
to control over indicators compared to a set of limit values. The monitoring system alerts responsible
officers about the facts within or beyond permissible limits and saves files that contain the
measurement data. Generally, data analysis is non-automated and carried out post factum rather
than in the real-time mode. Systems of continuous monitoring of the technical condition of structures
need improved data monitoring, analysis and storage processes as well as the system of their immediate
retrieval. Besides, the above procedures need a thorough assessment. Obviously, any advancement
of technologies improves data processing (data collection, analysis, storage, presentation);
therefore, issues of monitoring and operation of a sustainable system are to attain a new level.
The information support of the system of continuous monitoring of the technical condition
of structures is viewed from the perspective of Information Flow Processing (IFP) and SCADAsystems.
Contemporary SCADA-systems are widely used to control and manage the industrial environment
of plants and factories.
Peculiarities of the system of continuous monitoring of the technical condition of structures
consist in the fact that this system does not produce any direct influence on the subject under control.
Undoubtedly, certain features of the SCADA system architecture (alert generation, integration
with DBMS) might be considered in the course of development of systems of continuous monitoring
of the technical condition of structures.
Systems of continuous monitoring of the technical condition of structures process basic interconnected
monitoring events and generate more complex ones. Thus, the behavior of structures
exposed to diverse influences may be considered in a new perspective.
It is obvious that systems of continuous monitoring of the technical condition of structures
require a data warehouse responsible for managing complex events, data storage and presentation.
Data warehouses are to be the major component of systems of continuous monitoring of the
technical condition of structures.

The subject matter of the article is the system of continuous monitoring of the technical condition
of structures and its components. The authors also consider the approach to formation of the
data bank based on the cyclic data warehouse. The cyclic data warehouse (CS) is the basic element
of the data bank. Portions of data that represent continuous measurements taken in the non-stop
mode can be rapidly and efficiently saved into the CS system. CS is a file of a fixed size containing
a header and a sequence of objects. Data is supplied into the CS continuously in the cyclic mode:
incoming new data portions replace the outdated ones. New items are written over the old ones
when the storage time of the latter is expired. Data access in the CS is possible within the period
between the recording and replacement of the item.
The proposed option of the system of continuous monitoring of the technical condition of structures
ensures effective asynchronous data transmission between software modules and servers
and data consistency, because:
there is no more need for any additional data deletion operations;
the fixed size of a CS item allows fast data positioning in the CS file in the course of the random
access.
CS of sufficient size will provide for the possibility of a long delay in data transmission in case
of an abnormal situation occurring in the course of operation of the system of continuous monitoring
of the technical condition of structures.
Long-term operation of cyclic data warehouses has proven their effectiveness. For example,
a cyclic data warehouse is incorporated into a continuous monitoring system of the bridge over the
Matsesta River as the core data bank element.
