The development of a new regulatory base in the field of ropeways construction in the Russian Federation is currently coming to an end. Federal legislation defines the following priorities: updating of Construction Norms and Regulations and state standard specifications, energy saving and energy efficiency, converging Russian and European Union standards (including standards for building design - Eurocodes). This work should be completed in 2014. Experience in designing and coordinating passenger ropeways projects may lead, after analyzing the current status of regulatory legal base, to the following suggestions: simplifying the order of ropeways registration and commissioning for the reduction in administrative resource; new regulatory base should include the links to appropriate Eurocodes (a list of which is provided in the article). Operating personnel and designers might also find useful clarifications on the application of Eurocodes and the links to the corresponding Russian normative documents, which regulate design, calculation and control of both the ropeway and its separate parts. Absence or under fulfillment of such rules (for example, as in the case of the method of calculating construction during various working/non-working ropeway modes) should lead to their further development, which may be carried out by a combined group of ropeway designers, ropeway technologists and other related specialists; expanding security rules for passenger, cargo and ski lift ropeways on other types of cable transport, such as APM-ATS systems, which may be used throughout the Russian Federation in the future.

The theory of plates and shells is the most important application of the theory of elasticity. Rectangular slabs of average thickness are quite widely in construction, engineering and other fields of modern technology. Calculation of such structures cannot be conducted on the basis of the classical theory of bending of thin plates. In order to obtain a reliable picture of stress-strain state of a plate with average thickness, it is necessary to use different versions of improved theories. The aim of this work is the use generalized equations of the finite difference method (FDM) to calculate the dynamic loads of the plates average with thickness basing on the Reissner theory. On the basis of the developed algorithms computer programs have been worked out for calculating the dynamic load of bending plates of average thickness. The algorithm of calculating the dynamic load of bending plates of average thickness according to generalized equations of FDM can be recommended for practical use in frames of studying process.

In the modern construction, shipbuilding, mechanical, aircraft engineering and other fields of industry structures in the form of shells, including orthotropic shells, gained widespread currency. In order to raise their rigidity they are strengthened by reinforcing elements (ribs). In the process of shell constructions’ design the choice of rational construction parameters is very important (rational placement of ribs, their rigidity, curvature). The volume of the shell material is usually a minimalised efficiency function. At that the limit values of stress level in the shell and its stability are the restrictions. It is proposed to use variation and parametric method for choosing the angle and reinforcements by stiffening plates so that the shell construction would not lose its stability and reliability. The applied method with change of continuation parameters gives a scheme of coordinate-wise incline, which provides relative simplicity of choosing rational construction type in case of the given loads and restrictions on its stress-strain state.

The paper presents calculations of the punching girderless monolithic slab with transverse reinforcement under the action of a concentrated force in accordance with the applicable regulations. The authors specify the circumstances that may limit the use of the certain sizes of spans of beamless floors. The influence of various factors on ensuring the strength of the joints of columns and ceiling is obserced, such as the class of the concrete slab thickness, the presence of transverse reinforcement. In this paper the calculations of the burst strength were performed for girderless slabs of the thickness 20, 21 , 22, 23, 24 and 25 cm of concrete classes B15, B20, B25, B30 and columns of square section with the side b = 30 cm. The cells of 5 × 5, 6 × 6, 7 × 7, 8 × 8, 9 × 9 m were analized. Bending moments were not taken into account. The utmost bursting effort for various classes of concrete slab thickness and the absence or presence of transverse reinforcement were discovered. The limiting uniformly distributed loads for plates with different grid of columns were calculated. It was found out that in case of the size of the cells up to 5 x 5 m inclusively, you can use all the above concrete classes and slab thicknesss. But in case of the cells of 9 x 9 m and more the use of overlap without capitals is problematic because of the impossibility to ensure the burst strength without special design solutions. Some of contemporary ways to expand the use of overlap without capitals are: the use of high-strength concretes, application of stiff reinforcement in the area of joint of stiff reinforcement, fiber reinforcement and the use of prestressed reinforcement.

Two-sided evaluations based on the variational formulations of integral equations for the stability of elastic rods

The author considers the method of two-sided evaluations in solving the problems of stability of one-span elastic non-uniformly compressed rod with variable longitudinal bending rigidity in case of different classic conditions of fixation of the rod ends. The minimum critical value of the loading parameter for the rod is represented as a problem of calculating minimum value of the functional corresponding to the Euler equation, which is the same as the integral equation for the rod stability. Using the inequalities following from the problem of the best approximation of a Hilbert space element through the basic functions, the author constructs two sequences of functionals, the minimum values of which are the lower evaluations and the upper ones for the required value of the loading parameter. The basic functions here are the derivative forms of the stability loss for a rod with constant cross-section, compressed by longitudinal forces applied at the rod ends. The calculation of the lower bounds value is reduced to the determination of the maximum eigenvalues of block matrices. The elements of the aforesaid matrices are expressed through the integrals of basic functions depending on the type of the fixation of the rod ends. The calculation of the upper bound value is reduced to the determination of the maximum eigenvalue of the matrix, which almost coincides with one of the modular matrices. It is noted that the obtained upper bound evaluations are not worse than the evaluations obtained by the Ritz method with the use of the same basic functions.

In the following article the authors continue investigating elliptical equation. Let P be an unlimited cylinder in the space R3, the cross-section of which is a regular dodecagon. The authors have previously estimated linear self-conjugate uniformly elliptic equation of second order in the cylinder and obtained theorems on the growth of the solution in bounded domain. In order to prove the theorems we have to continue solving the differential equation and its coefficients for the whole space Rn.
Let L be a second order linear differential operator in a divergence form which is uniformly elliptic and h is its ellipticity constant. Let u be a solution of the mixed boundary value problem in P for the equation Lu=0 (u>0) with homogeneous Dirichlet and Neumann data on the boundary of the cylinder.
In this paper the solution for mixed boundary value problem is continued from the cylinder to the whole space R3.
The solution of the mixed problem has connection with the notion of the mathematical tessellation. This tessellation is a sum of nonintersecting regular dodecagons and triangles filling the whole space R2

In the present paper the researches consider the behavior of the class of operators defined by exponential summing methods of Fourier series. The authors examine exponential means of certain Fourier series. The convergence in Lebesgue points is investigated. The operators determined by the convergence are known as the means of Poisson - Abel and they play the substantial role in different questions of the analysis. Though even the most simple and natural extension is not fully investigated. Conclusions of the considered theorem follow from the results for general infinite convex or piecewise convex summing sequences; the given results are also of individual interest. The analogue of the theorem is specified for exponential means of conjugate Fourier series. The examples of exponential means are given, which satisfy the hypotheses of the considered theorems and are also of individual interest. The obtained results are valid, in particular, for the generalized Poisson means. The authors also give an example of a polynomial-exponential method of summation.

The features of behaviour of a thin-walled cold-formed C-purlin

Nowadays thin-walled cold-formed profiles are widely used as bearing structures of buildings. The features of these profiles are little thickness and complicated cross-section shape. These features influence the behaviour of the structures made of cold-formed profiles. It is an often situation that we can not apply load directly on the element in the shear center due to its complicated shape and boundary conditions, such as support fixation. Thus, the purlin experiences a combined action of bending and restraint torsion. Besides, the distortion of purlin occurs and in this case the Vlasov’s theory of thin-walled elastic beams is not applicable. In this paper the analysis of cold-formed C-purlin is considered. The results of physically and geometrically nonlinear analysis are represented. The components of the stress state of purlin are determined. An estimation of the influence of cross-section distortion on the angles of rotation about longitudinal axis of purlin is done. The buckling analysis according to Russian standards SNiP was done.

Interaction between grouted prestressed anchor and surrounding soil body with account for creep and structural shear strength is investigated in this paper. The behavior of the system is described by the modified rheological Bingham-Shvedov equation. It is shown that fixation of initial tension or its periodical variation causes problem of anchor creep and stability, and fixation of initial displacement causes initial stress relaxation of the system “surrounding soil body - anchor - tendon”. The relaxation time significantly depends on elastic-viscoplastic properties of surrounding soil, diameter and length of anchor and tendon, and its elasticity. Account for viscoplastic properties of soil with the structural shear strength leads to residual stresses in the system. The solutions of these problems can be used for quantitative estimation for stress-strain state of the system. This estimation makes it possible to calculate long-term deformation and bearing capacity of anchors, stress relaxation and residual stresses. The problem of interaction between anchor and the surrounding soil is solved in this paper. It is shown that displacement of anchor and stresses in the soil depends on different parameters, such as soil properties, geometrical properties of the anchor, selection of design model and account for ultimate stiffness of the anchor. Also this solution is basic for problems of creep and stress relaxation in the system. The process of formation of the stress-strain state around the anchor could demonstrate decaying, constant or progressive velocity highly depending on rheological processes in the soil body that may at the same time be accompanied by hardening and softening processes.

The article discusses possible defects of exterior walls of buildings that can occur in a multilayer brick masonry. The article is based on the inspection materials of the school building located in Bronnitsy, Moscow Region. The reasons of brick masonry defects are considered and analyzed. An external wall strength calculation of the stairwell of the building is given, confirming the reasons for the formation of defects in the masonry. The static calculation results of the exterior wall of the building stairwell revealed the presence of tensile forces in the zone of window sill of the lower window opening of the exterior wall of the building. The calculations of masonry tensile showed that load bearing capacity of the masonry in window sill zone is not provided. Thus, the calculation is justified for cracks in the window sill area of the calculated wall. The appearance of hairline cracks on the outer face of a decorative protective layer multi-layer masonry is due to the thermal deformations, the manifestation of which is enhanced by the presence of the layer of effective insulation located behind the layer of masonry and embarrassing action of rigid ties on the development of thermal deformations.

In this article currently central tasks of successful industrial development of wall ceramics are viewed. The main problems connected with the use of classic argillous raw material for wall ceramics - clayey soils are pointed out. Generally these problems are connected with the fact that deposits of clayey soils are situated on arable areas, they have small areas of occurrence, their consistence and qualities are very changeable because of genesis. Taking this into consideration, it was shown that argillous raw material including claystone-like clays, argilliths, clay slates, aleurolites and in-between types of solids are of the utmost interest. Five kinds of deposits of this material are pointed out and characterized. These are traditional deposits of clay slates, which were proved as ceramsite raw materials; anthropogenic deposits of pit heap of the Eastern Donbass; cocurrent raw materials and ettle while developing limestone and sandstone deposits; ettles of screening of argillith and clay slates appearing while their preparing for expanded clay production after the dry manner; tails forming while coal cleaning and which are generally made of argillous raw material. The existing difficulties connected with the terminology of this range of raw materials are pointed out in this article, that is why characteristic of each type with regard to features of the mineral composition, structural features, technological properties are offered. It is noted that in regard to mineralogy distinct diagnostic features providing difference between solids of the range: claystone-like clay- argillith- clay slate can be hydrous micas and micas. The results of the works in this regard allowed offering a method of testing lithoidal raw material for producing wall ceramics materials. It is noted that in the technology road-map the key distinction between claystone-like clay, argillith and clay slates is that while comminuting claystone-like clays the strength of samples burning in the same conditions is initially relatively high and increases insignificantly, for argilliths the reduction range is a shaping factor for attainment of necessary strength, for clay slates the reduction range is also a shaping factor, however, strength characteristics of the samples are much lower. High perspective of this raw material usage for wide assortment of wall ceramics products and tile is proved.

One the new stage on nuclear medicine development there is a need to solve a number of tasks. The choice of radiation shield materials is an important task, because they to a large extend determine radiation safety in the process of operation and volumes of radioactive emissions in case of decommissioning. The stage of decommissioning is final in operation life of such installations. In the article the authors present an estimation of the producer of cyclotrons PETtrace 880 on radionuclides, which arise in the composition of concrete biological shield of cyclotron after decommissioning in Pet-centre of Russian Oncologic Scientific Center named after N.N. Blokhin. It was shown, that the data of the producer can lead to underestimating the volumes of radioactive waste. The tasks for further investigation on the problem are outlined. The authors defined the role of induced activity estimation on the stage of design and decommissioning of the cyclotrons for radiological safety. For designed objects the elemental composition of protecting constructions should be included in design documents. The choice of the composition should take in account the activation capacity of doping and tracing elements. The adequate estimation of induced activity should result in optimization of design and construction solutions. Such an approach will allow realizing the future stage of decomposition in more efficient and safe way by reducing radioactive waste and dose costs for staff and population.

The essential issue of engineering safety of high dams is substantiation of the seepage conditions of the dam - foundation system. In most cases, a violation of the filtration mode leads to disruption of the hydraulic structure. The authors analyzed the methods of mathematical simulation of a filtration mode for large dams’ foundations basing on finite element method. Up-to-date computational capability permits solving seepage problems in 3D transient formulation. The possible reasons for filtration mode disturbance in foundations of large dams are observed, as well as the corresponding methods of analytical forecasting for the parameters of inappropriate development of filtration processes. Application of the universal industrial-strength software complexes makes it possible to combine on a single software platform the seepage modeling with other methods of design-basis validation of hydraulic structures, such as computations of stress-strain state, strength and stability of the dam - foundation system. The analysis results should be further used in the calculation of the stress strain state of the structures.

The article presents and analyzes experimental studies of the distribution of ink in the water and the explosive combustion of methane-air mixture. The authors described the processes of explosive mixtures’ formation in a room in case of methane leakage. The article also presents the visualization of the formation process of explosive mixtures. The mathematical model and calculation model adequately describe the process and confirm the results of the experiments. The coefficient of turbulent diffusion under the given conditions is indirectly determined. Explosive mixtures usually form accidental leaks of combustible substances from household stoves in the residential sector. The consequences of such accidents are human losses and material damage. As the analyses have shown the formation of gas-air mixtures of combustible substances is affected by: turbulent diffusion coefficient, the parameters of the sources of accidental releases, the physical properties of gas-air mixtures and other. Explosive substances are not visible to the human eye. In order to visualize the physical process we will use the model distribution and dissolution of ink in water. Based on the analysis of the works of different scientists it was concluded that the laws of distribution of liquids and gases are similar. The experiments were carried out in order to study the distribution of ink in the water and explosive combustion of methane-air mixture to determine and describe the process of formation of explosive mixtures in a room in case of methane leakage. The coefficient of turbulent diffusion is a key parameter that can accurately predict the development of these emergency situations.

In the article the main design errors of the systems of rubbish disposal over recent years are considered, in which the systems of water supply and water disposal had a supporting role. The main problems arising during operation of dry cold refuse chutes, the deprived new technical solutions on water supply and sewerage are shown. Solutions of the main task of ensuring sanitary and hygienic safety of people living in the building by installation and operation of special clearing devices with a supply of cold and hot water are provided. They allow placing the necessary equipment for cleaning an internal surface of a trunk of a refuse chute in the compact case. It will allow not only to get rid of unpleasant smells, but also will prevent distribution of rodents and insects in the whole residential building. Also this device allows fighting against obstruction of a trunk of a refuse chute large-size subjects that isn’t a rarity recently at operation of a dry cold refuse chute in a building. Much attention is paid to the organization of fire safety in case of possible fire in the collecting garbage camera that can lead to smoking of staircases and poisoning with carbon monoxide of people living in the building. The technical solutions are given, which allow to refuse using sprinkler fire extinguishing system because of its inefficient work for fire extinguishing in the collecting garbage camera. It is offered to pass to the deluge systems, allowing to extinguish a fire either automatically with the help of smoke sensor installed indoors, or by means of the controlling service personnel in the garbage container. The special attention is paid to consideration of the questions of suppression of possible ignition in a refuse chute trunk, which can occur at ejection of a burning subject in the trunk hammered with large-size garbage. As the solution to this problem it is offered to use also drencher fire extinguishing and special gas analyzers for catching of vapors of a caustic smoke, which can suddenly appear and lead to serious incidents.

Hydraulic engineering models are usually calculated according to Fraud law. Though in the process of small size models operation also viscosity and service tension forces become essential and we can’t neglect them.
The article considers the influence of viscosity and surface tension on discharge coefficient in case of efflux from under the gate. In the article the technique of carrying out experiments is stated, the equation is presented, which considers the influence of all factors: pressure, speed of liquid, liquid density, dynamic, superficial tension, gravity acceleration, unit discharge, width of the course, opening height. The surface tension and the liquid density for the used liquids changed a little. The gate was established in a rectangular trough (6000×100×200).
It is shown that with the increase of Reinolds number (at a relative opening a/H = 00,04…0,03 and Webers number
We > 250) the discharge coefficient rises and no longer depends on the Reinolds number, at Re > 2000 and Webers number (at constant values of Reinolds numbers) practically does not influence the discharge coefficient.

The purpose of this research is to develop a new fuzzy group decision making algorithm and apply it to select the most preferred alternative for sediment management in the Dez dam reservoir. In this way, nine potential alternatives for sediment management in the Dez reservoir and four criteria (technical and executive requirements, economic factors, social welfare, environmental impacts) are selected. In order to evaluate different alternatives, firstly, the collective group weight of each alternative is calculated considering assessment of a group consisting of four criteria. And after that, the best alternative is selected using the proposed fuzzy group decision making methodology. The results of this study showed the efficiency of the application of fuzzy group decision making in sediment management. Application of the proposed method helps to balance the whole criteria and to select the best alternative.

Road transport compared with rail, air and water transport is currently the most dangerous mode of transport. In recent years, more attention has been given to the issues of comfort and active safety of vehicles. Safety of the vehicle is a complex problem, the solution of which is primarily concerned with improvements aimed at enhancing active safety system driver - vehicle - road. One of the main vehicle performances significantly impacting road safety and the environment, is a high-speed mode. Active safety car driver includes the ability to assess the situation on the road and choose the safest mode of movement, as well as the possibility of the vehicle to implement the desired safe driving mode. Analyzing the causes of road traffic accidents submitted on the official websites of traffic police of the Perm region and Russia, it can be concluded that often carelessness and negligence of the driver is not the reason of an accident, but his inert perception, resulting in delayed response to rapidly changing traffic conditions. An average driver does not have the ability to instantly perceive suddenly appearing obstacles and quickly take measures to ensure the car’s handling and implementation of safe motion path. For this purpose we developed a modern technical means installed on a highway in the form of «vibrolane», with a driver fatigue monitoring system, which is aimed at preventing the driver wearied while driving behind the wheel from a possible departure to the oncoming lane or exit to the side of the road at driving on the hump. Thus, the proposed security system will reduce the number of accidents.

The monitoring procedure is an integral part for tracking the results of tendering. It’s also necessary for patterns’ identification to make subsequent legislative adjustments. This article includes the Western experience analysis of the state contracts’ tracking with underlining of its main features. The U.S. Federal contract system includes the Act called «The Office of the U.S. state order», which was adopted in 1974. The Act requires creating a system for collecting information about federal government contracts. It is OMB’s obligation. Federal data bank of the state order was created in 1978. The control system of public procurement procedures, serving in Germany, meets the requirements of the EU, but has certain specifics. All the organizations, which are equated to government customers in accordance with the definition of the European Union, are in the sphere of public procurement procedures’ control system. Thus, the state customer is also a number of private entities. The control system includes two instances: 1) the appellate court, which exists in the form of an independent institution; 2) the court, which exists in the form of a judicial authority. The governmental experts’ and scientists’ organization called “State orders forum” is very effective and popular in Germany. Its members exchange their opinions on new developments in public procurement within the country and abroad. The article includes the analysis of the existing public orders monitoring procedures. Also the laws of procurement implementation, which exists at the stage of bidding and contractual obligations, are highlighted in the article. The consequences of ignoring the existing problems of public order in Russia are systematized. The main drawbacks of the state order control system are identified. In this article the existing public systems of the state order monitoring in Russia are inventoried. The requirement of cardinal processing the format and scope of the information is provided. Also the rules, which should serve as a new base for the state order controlling system, are formulated. What is more, the article includes the Moscow Construction Department as an example of the system tracking the procurement procedures. We offer a hypothetical model of the state order economic examination, based on the resulting data rates: price reduction in tendering; the number of participants in the tendering; execution of the contract term; life cycle costs; the quality of products; the presence of documented violations. Each indicator is assigned an importance factor in achieving the overall efficiency, which is defined by experts with the participation of government customers’. Determination of the complex efficiency index occurs by summing the obtained parameters. The results are obtained. The conclusions are formulated. Thus, the vector of the state order analysis direction from monitoring data to the hypothetical model of efficiency examination is defined.

On January 1, 2014, Federal Law No. 44-FZ On the Contract System in the Procurement of Goods, Works and Services to Meet the State and Municipal Needs (hereinafter, the Contract System Law) came into force. It is the new law on public procurement, which improved tendering procedures, implemented new types of organization and the rules of procurement, as well as adopted new tender evaluation criteria. Such innovations will make the procedure of procurement more transparent and efficient and improve the trading mechanism itself, thus, putting its operation to a brand new level. This article will show tender evaluation criteria based on the previous law (Federal Law No. 94-FZ dated July 21, 2005, On the Placement of Orders for Delivery of Goods, Performance of Works and Rendering of Services for the State and Municipal Needs (hereinafter, the Public Procurement Law) and the new law (the Contract System Law) on public procurement, their comparative analysis and the ways to improve open tender evaluation criteria. Open tender is still challenging in terms of organization and long-term with respect to the period for tendering procedures stipulated by the laws. However, as compared to the Public Procurement Law, the Contract System Law provides for twenty-day period for submission of competitive bids before the date of opening of envelopes from the date of posting the notice of procurement in the unified information system. Criteria, their types and significance applied by the customer based on the feasibility of selection depending on the specific tendering play a primary role at this stage of tendering process. At present, pursuant to Part 4 of the Article 32 of the Contract System Law, the customer must use at least two evaluation criteria in open tendering and the contract price should be one of them. Innovation of the laws also lies in the fact that the law establishes so-called cost and non-cost tender evaluation criteria, namely: the contract price; quality, functional and environmental characteristics of the procurement target; qualification of procurement participants, including availability of financial resources, equipment and other material resources necessary for execution of the contract, presence of goodwill, professionals and other employees of a certain skill level.

The present work is concerned with statistical analysis of functional characteristics’ estimation of the outlet flow with the purpose to transfer to the analysis of multiphase series-connected queuing net, where a definite queuing system will be considered as a phase. The authors observe statistical methods of fitting criteria use in the process of parametric hypotheses check. The article presents a series of simulation experiments and statistical analysis aimed at to determining the parameter dependencies of the queuing system with storage hopper and interval delay in the beginning of service basing on the condition of identity types of incoming and outgoing flows of applications. On the basis of the expected incoming flow and servicer, the authors defined the method for calculating the maximum possible interval between the beginning of service system and effluent applications in relation to the type of exponential distribution. The study also developed a technique to obtain the parameters of the statistical null hypothesis using approximation approaches based on least squares method and the integral method.

In the process of organizing the cooperation of participants of construction special attention should be paid to logistic connections, which formed in frames of planning, management and control of material, information and financial resources. Logistics in the construction is of integrated character and is carried out in frames of different modules cooperation. In the given article the authors consider the cooperation of organizations-participants of a big construction company, which includes enterprises and organizations - suppliers of materials and raw materials for construction industry, transport organizations and organizations performing construction and installation works. Modular decomposition of production and logistic construction processes is conducted. The authors suggest a solution for the problem of expedience of putting a construction object into operation with the help of cooperation organization of the participants basing on the normative document - industrial transport and technological modulus. It is planned to control of schedules and plans in such time scale, in which they are made, by means of "virtual enterprise".
