ARCHITECTURE AND URBAN DEVELOPMENT. RESTRUCTURING AND RESTORATION

Wood in the modern architectureof small forms

The modern world dictates severe conditions, involving people in a continuous process of changes in the environment. Active building and construction work, urban densification are rapidly transforming environment, creating a new architectural space with intense impact on people. In this regard, there is much tension around the issue of provision of urban amenities, forming comfortable environment for a full human life. The comfort of the urban environment is determined by a set of visual perception of the constituent elements of this environment: architecture, design, landscape and their harmonious unity with nature. A remarkable component of visual perception, making urban space aesthetically appealing, is small architecture.Small architecture in Russia has always played a special role. Being perceived in the context of space, creating at the same time a certain mood and emotions, small forms diversified architectural environment, making it aesthetically appealing. The question about the direction of urban policy in the field of provision of urban amenities was made in 1921, when the first Congress on improvement of populated areas took place. With this legislation originated overall urban development approach as inseparable system layout of the city, its architectural appearance and landscaping. Architectural workshops developed model projects of small forms with recommendations for improvement, which helped to inexpensively create individual features in urban development. At present, the provision of urban amenities have moved to a new level, becoming more grandscale, capital-intensive.The main requirements for small architectural forms are to create a harmonious space, the fusion of architecture with the natural elements. The most harmonious perception of small architectural forms in the environment is achieved through the use of natural building materials. The use of natural materials in urban environment represents nature, creates a comfortable environment psychologically close to a person. Wood, among other natural materials, has an undoubted advantage. Absolute compatibility, unique design quality, expressive possibilities of the material and its ability to form a comfortable living environment, harmoniously combined with other materials, provide greater demand for wood in modern architecture.In the architecture of small forms wood is used everywhere: on the territories of residential quarters, parks and recreation areas, areas of office and commercial development, road environment, etc. A leading role in shaping the public space belongs to small structures for various functional purposes, such as benches, gazebos, sheds, sports facilities, children’s playgrounds.In the modern wooden architecture of small forms two directions are clearly traced. In the first one there is the desire to escape from the boring similar forms, transforming small architectural forms in art objects representing not only material, but also artistic value. The second direction is based on the centuries-old practice of folk art. Having been formed for centuries folk culture and national traditions fully meet the artistic tastes of the modern society. Summing up, it should be noted that the use of wood in architecture of small forms is a universal solution to shape the ecological framework of the urban environment, which is especially important in solving the problems of the modern city.

Precast-monolithic construction is becoming an increasingly popular form of housing. The wide distribution of this type of construction is explained by the possibility to successfully combine the advantages of precast and monolithic construction, at the same time reducing their disadvantages. Though there is a significant lack of data, including experimental data, for objective assessment of the stress-strain state of precast-monolithic floor structures. In order to investigate the structural reliability of the bolt joint of a bearer with a column in a precast-monolithic building a series of experimental investigations were carried out in the laboratory of testing the building structures of the Siberian Federal University.One of the main conclusions is that the bolt joint of a bearer with a column is characterized by sufficient rigidity, crack resistance and bearing capacity. The results of the given work have proved the data obtained in previously conducted investigations on a fragment of a precast-monolithic ceiling.

In recent time there is a very great interest in the study of differential equations of fractional order, in which the unknown function is under the symbol of fractional derivative. It is due to the development of the theory of fractional integro-differential theory and application of it in different fields.The fractional integrals and derivatives of fractional integro-differential equations are widely used in modern investigations of theoretical physics, mechanics, and applied mathematics. The fractional calculus is a very powerful tool for describing physical systems, which have a memory and are non-local. Many processes in complex systems have nonlocality and long-time memory. Fractional integral operators and fractional differential operators allow describing some of these properties. The use of the fractional calculus will be helpful for obtaining the dynamical models, in which integro-differential operators describe power long-time memory by time and coordinates, and three-dimensional nonlocality for complex medium and processes.Differential equations of fractional order appear when we use fractal conception in physics of the condensed medium. The transfer, described by the operator with fractional derivatives at a long distance from the sources, leads to other behavior of relatively small concentrations as compared with classic diffusion. This fact redefines the existing ideas about safety, based on the ideas on exponential velocity of damping. Fractional calculus in the fractal theory and the systems with memory have the same importance as the classic analysis in mechanics of continuous medium.In recent years, the application of fractional derivatives for describing and studying the physical processes of stochastic transfer is very popular too. Many problems of filtration of liquids in fractal (high porous) medium lead to the need to study boundary value problems for partial differential equations in fractional order.In this paper the authors first considered the boundary value problem for stationary equation for mass transfer in super-diffusion conditions and abnormal advection. Then the solution of the problem is explicitly given. The solution is obtained by the Fourier’s method.The obtained results will be useful in liquid filtration theory in fractal medium and for modeling the temperature variations in the heated bar.

The subject of this paper is the stability and strength of cold-formed and perforated steel sigma-section columns with steel sheathing of different thickness. Ceilings with and without steel sheathing of different thickness are tested to failure in compression on a laboratory machine, which was based on a manual hydraulic jack. Series of 4 experiments with full-scale walls (2.5 m height) were carried out. Also, for examination of the role of boundary conditions, the sheet in a ceiling is either left free or connected to base with screws.In civil engineering there are many experiments and methodologies for calculating the strength and buckling of ceiling with the sheathing of various materials, such as oriented strand board and gypsum board. However, for producing superstructures of ships the materials with high plastic properties and strength characteristics are required. For example steel possesses such properties. It was the main reason for conducting a series of experiments and studying the behavior of cold-formed steel columns with steel sheathing. During the experiments the deformation of the cross-section of three equally spaced cross sections was determined, as well as the axial deformation of the central column in the ceiling with steel sheathing.The test results showed the influence of the thickness of sheathing and boundary condition of a sheet on the strength and buckling of ceiling. According to the results of the tests it is necessary to evaluate the impact of the sheathing made of different materials and if necessary to carry out further tests.

When a long pile is interacting with the soil, the combined force applied to the pile head is distributed among the side face and the pile toe inhomogeneously. The toe gets not more than 30 % from the general force, which doesn’t let using the reserves of the bearing capacity of relatively firm soil under the fifth pile. Account for the depth of the pile toe and the dead load of the soil allows increasing the bearing capacity of the soil under the pile toe and decrease the pile settlement in general. For the quantitative estimation of these factors it is necessary to solve the task on the interaction of the rigid long pile with the surrounding soil, which includes under the pile toe, which is absolutely rigid round stamp.The article presents the formulation and analytical solution to a quantification of the settlement of a circular foundation with the due account for its depth, basing on the development of P. Mindlin’s studies as well as the interactions between a long rigid pile and surrounding soils, including under pile toe.It is proposed to compare the estimated value of stresses under the heel of pile with the initial critical load for the round foundation to check the condition that the estinated value is less than the intial critical one.

Transfer of the load from the wheels on the rail occurs at a very small area compared with the size of the wheels and rails. The materials near this site have a very large voltage. Determination of contact stresses is complicated by the fact that the magnitude of these stresses in the rails under actually revolving wheel load exceeds the yield and compressive strength of modern rail steel. We should note that the metal of the rail head, experiencing contact stresses, especially when the location of the pads is closer to the middle of the rail head, works in the conditions close to the compression conditions, and therefore can withstand higher voltage without plastic deformation than the standard compressible sample. But, as a rule, the observed hardening of the metal in the zone of contact stresses and lapping at the edges of the rail head indicates the presence of plastic deformation and, consequently, higher stresses in the wheel-rail contact zone than the yield strength of the metal rail even in the conditions of its operation in the rail head.The use of the design equations derived on the basis of the Hertz theory for metal behavior in elastic stage, is valid. The reason is that each individual dynamic application of wheel loads on the rail is very short, and the residual plastic deformation from the individual loads of the pair of wheels on the rail is actually small. This elastic-plastic deformation of the rail becomes visible as a result of gradual gaining of a missed tonnage of rails and wheels respectively. Irregularities on the running surface of the wheels are of two types. The most common are the so-called continuous bumps on the wheel, when due to the uneven wear of rail the original shape of the wheel across the tread surface distorts. But nowadays, more and more often there occur isolated smooth irregularities of the wheel pairs, due to the increased wear of the wheel because of the stopping and blocking of wheels of the vehicles - slides (potholes), etc.The motion of the wheels with irregularities on the surface of the rail leads to vertical oscillation of the wheel, resulting in the forces of inertia, which is an additional load on the rail. In case of movement of the wheel with isolated roughness on the tread surface of the slide there is a strike, having a very large additional impact on the rail. Such attacks can cause kinked rails, especially in the winter months when there is increased fragility of rail steel, because of lowered temperatures. This is an abnormal phenomenon and occurs relatively rarely, at a small number of isolated irregularities on a wheel of the rolling stock. As correlations connecting the contact force and local deformation in the interaction of the wheel-rail system, we use the quasi-static Hertz’s model, linear-elastic model and two elastoplastic contact models: Alexandrov-Kadomtsev and Kil’chevsky. According to the results of Loktev’s studies ratios of the contact Hertz’s theory are quite suitable for modeling the dynamic effects of wheel and rail for speeds up to 90 km/h for engineering calculations. Since the contact surface is homogeneous and isotropic, the friction forces in the contact zone are not taken into account, the size of the pad is small compared to the dimensions of the contacting bodies and characteristic radii of curvature of the undeformed surfaces, the contacting surfaces are smooth.When train is driving, the position of the wheelset in relation to the rails varies considerably, giving rise to different combinations of the contact areas of the wheel and rail. Even assuming constant axial load the normal voltage will vary considerably because of the differences in the radii of curvature of the contacting surfaces of these zones. Thus, the proposed method allows evaluating the influence of several types of wheel defects on the condition of the rail and the prospects of its use in the upper structure of a railway track on plots with different speed and traffic volumes. Also the results can be used to solve the inverse of the considered problems, for example, when designing high-speed highways, when setting the vehicle speed and axle load, and the solution results are the parameters of the defects, both wheelsets and the rails, in case of which higher requirements for the safe operation of railways are observed.

The article examines the dependence of the hydraulic friction coefficient of open laminar uniform streams on the relative width of channels with smooth bottom. The article presents the functional dependence that describes the hydraulic resistance in open channels with smooth bottoms.The experiments were carried out in a rectangular tray (6000×100×200). Aqueous solutions of glycerol were used as working fluids. The superficial tension and liquid density for the used liquids changed a little. The article declares that the coefficient of hydraulic friction λ in the zone of the laminar flow depends on the relative width of the channels with smooth bottom. In the article it is also shown that the Charny formula satisfactorily agrees with the theoretical formula and with the experimental data.

In course of time in structural elements of engineering technical systems defects and damages are accumulated, which is caused by loadings and environmental influence. The defects are any inconsistencies with normative documents, and damages are discontinuances of structure. The defects and damages lead to decrease of operational properties of structures (their bearing capacity, waterproofing, thermal resistance, etc. The occurrences of such character are called physical wear.In the article the authors show the possibility of phase trajectory use of the processes of physical wear, creep and cusp catastrophe for determinating the critical timepoint, corresponding to the beginning of the system damage catastrophic growth. The alternative approach to the description of the processes of physical wear and creep of pavement consisting in comparison of asphalt concrete creep curve and the curve of the mathematical model of cusp catastrophe, is received. The applied synergetic approach gives us the chance to improve the existing and create new methods of pavement resource forecasting and assessment of physical wear of any technical constructions.

Logistics of production processes at a gas station is a critical point in the system of petroleum products, on the operation of which the effectiveness and sustainability of the transport sector depends. The provision and supply of road transportation of petroleum products is one of the most urgent tasks.Technological processes of reception, storage of fuel and refuelling of motor vehicles on petrol stations needs a scientific study of their structure and organization. At the design stage of a gas station, it is necessary to consider quite a lot of different factors: the configuration of the area under the gas station, the scheme of arrangement and the number of fuel dispensers, the trajectory of motion and the design of vehicles, calls to the station, distance between cars on duty, between the elements of buildings and equipment, as well as the requirements for fire, building, public, sanitary-epidemiological and state regulations. Therefore, the designer has a great opportunity for varying the parameters of the elements of the station, especially when considering the characteristics of the fueled vehicles.Typical projects at a same power station include various sizes, the seizure of land to build a station changes from planning decisions and the locations of all its technological elements. For increase of functioning efficiency of transportation systems of petroleum products in modern conditions on the basis of the design and technical innovations it is necessary to conduct special studies.Research planning decisions for a refueling station led to the conclusion that the placement of technological equipment in the refueling area has a certain impact on the length of vehicles service. Improving the layout of the refueling zone several times reduces the loss of the components of the refueling cycle time and increase the capacity of the station.Information base describing the stages of a gas station includes parts of refueling cycle time and allows choosing the optimal variant of fuel dispensers at the fueling area. The rational layout of columns can reduce the time of customer service and increase the capacity of the object.

The search for inner factors of the development and their control are invariant in the current conditions for fastening the processes of overcoming the crisis. In order to solve the contemporary problems quality changes are necessary. Today in the basis of such changes advancing the state participation in regulating the economy in general and advancing the state order in particular are considered. Though the possibilities of construction development are rather great, it has always been impossible to achieve the essential results without state support.The authors considered the experience and problems of using sovereign state funds in construction in the modern conditions. The ways to efficiently apply the reserves as system solution of national economy problems are investigated - support of construction sphere allows facing the challenges of macroeconomy crisis. The authors offer the means of quality change of state order content not only in solving general branch questions, but also the questions of system character of control development of intangible assets.

The author examined the variations of Russia’s social and economic development in the following years оn the basis of synergetic scenarios application method. The first scenario is related to the transformation of Russia into raw material resource base and а source of low-cost lаbоur force for the advanced nations of West and East, the loss of the country›s intellectual and cultural potential. The orientation towards innovative, scientific and technical development in the context of modern, post-industrial, information age is associated with the other scenario of social and economic development of Russia. The analysis of the successful experience of scientific and technical development of the USA and the USSR economies as а whole, and of the construction industry as оnе of the important economy directions, is а substantiation for the necessity of new industrialization in Russia, in the context of market and information age. The author advances а statement that Russia in 21st century needs to repeat the positive experience of industrialization and accelerated scientific and technical development of the Soviet Union. The problems facing Russia аrе construction of innovative industrial projects that meet the requirements of the world standards, implementation of largescale national programs, advancement towards the information society. The article emphasizes а thesis about the necessity to manage modern social and economic processes. It focuses the attention of scientists and expert managers оn I. Ansoff’s new management paradigm. The article pays special attention to the matters of modeling the changes in the construction industry complex of Russia, which is one of the most important branches of economy. Two alternative scenarios of the most general changes in construction industry аrе given in it.

The current problem for managers in logistic and trading companies is the task of improving the operational business performance and developing the logistics support of sales. The development of logistics sales supposes development and implementation of a set of works for the development of the existing warehouse facilities, including both a detailed description of the work performed, and the timing of their implementation. Logistics engineering of warehouse complex includes such tasks as: determining the number and the types of technological zones, calculation of the required number of loading-unloading places, development of storage structures, development and pre-sales preparation zones, development of specifications of storage types, selection of loading-unloading equipment, detailed planning of warehouse logistics system, creation of architectural-planning decisions, selection of information-processing equipment, etc. The currently used ERP and WMS systems did not allow us to solve the full list of logistics engineering problems. In this regard, the development of specialized software products, taking into account the specifics of warehouse logistics, and subsequent integration of these software with ERP and WMS systems seems to be a current task. In this paper we suggest a system of statistical analysis of logistics information, designed to meet the challenges of logistics engineering and planning. The system is based on the methods of statistical data processing.The proposed specialized software is designed to improve the efficiency of the operating business and the development of logistics support of sales. The system is based on the methods of statistical data processing, the methods of assessment and prediction of logistics performance, the methods for the determination and calculation of the data required for registration, storage and processing of metal products, as well as the methods for planning the reconstruction and development of the existing warehouses. The results of approbation of software for the logistics of designing large warehouses of metal trading companies are given.

The article focuses on the optimization of the earlier discussed computer method of obtaining new forms of polyhedra based on projective geometry drawings (trace Diagrams).While working on getting new multifaceted forms by projective geometry methods based on the well-known models of polyhedra on the first stage of the work it is required to calculate the parameters of projective geometry drawings, and then to build them. This is an often used apparatus of analytical geometry. According to it, at first the parameters of the polyhedron (core system of planes) are calculated, then we obtain the equation of the plane of the face of the polyhedron, and finally we obtain the equations of lines the next plane faces on the selected curve plane. At each stage of application such a method requires the use of the algorithms of floating point arithmetic, on the one hand, leads to some loss of accuracy of the results and, on the other hand, the large amount of computer time to perform these operations in comparison with integer arithmetic operations.The proposed method is based on the laws existing between the lines that make up the drawing - the known configurations of projective geometry (complete quadrilaterals, configuration of Desargues, Pappus et al.).The authors discussed in detail the analysis procedure of projective geometry drawing and the presence of full quadrilaterals, Desargues and Pappus configurations in it.Since the composition of these configurations is invariant with respect to projective change of the original nucleus, knowing them, you can avoid the calculations when solving the equations for finding direct projective geometry drawing analytically, getting them on the basis of belonging to a particular configuration. So you can get a definite advantage in accuracy of the results, and in the cost of computer time. Finding these basic configurations significantly enriches the set of methods and the use of projective geometry drawings.
