    Abstract. The problem of providing affordable and comfortable housing for citizens of Russia, despite the program of modernization of the construction complex adopted recently by the country government, remains quite acute. The analysis of the concept, principles and mechanisms of development and implementation of housing programs in the regions of Russia is made from the position of the biosphere compatibility paradigm for urban areas. The necessity of introduction of innovations into economic circulation at all stages - research, design, construction of socially important construction objects, consumption of an innovative product - is shown. The principles and necessary conditions ensuring the introduction of innovations during the implementation of programs and realities of the social component of the modern urban development are presented. When developing such mechanisms, the principles and methods of quantitative evaluation of the effectiveness of development programs, based on the doctrine of biosphere compatibility of cities and settlements developing human, can be used.
    Key words: biosphere compatibility, city functions, city planning, quality of life, development of a person.

    Abstract. On the basis of the analysis of cracks near the support and cracks adjacent to the concentrated load, calculation schemes (in the form of reinforced concrete constituent elements cut by two transverse sections which are located at a distance equal to stirrup spacing) for determining the elongation deformations of concrete along the axis of the cross bars in the upper and lower zones of reinforced concrete composite constructions in the "shear" span are considered. Resolving equations that close to the considered design schemes have been written that makes it possible to specify the actual stress-strain state of this structure during the loading. A new method of determining the shear stresses is proposed.
    Key words: inclined cracks, elongation deformations of concrete, reinforced concrete composite constructions, design models, resolving equations.

    Abstract. Two variants of determining the stiffness of structures and floors of buildings and facilities consisting of reinforced concrete planar stressed and frame elements with cracks are considered. A new variant of simulating the formation of inclined cracks with their designed parameters in planar and frame reinforced concrete composite structures under seismic impacts is proposed. On its base an alternative method of single vertical strips for determining the stiffness of reinforced concrete structures in areas with inclined cracks is presented; it comes to the scheme of a compound rod for determining the stiffness of reinforced concrete structures in areas with inclined cracks.
    Key words: reinforced concrete constructions, inclined cracks, composite rod, stiffness, seismic impact.

    Abstract. Solutions of the problem of experimental-calculation determination of a support moment of a cantilever beam loaded with concentrated force at its end including the optimal choice of coordinates of four references and parameters of transformation of references in case of insufficient accuracy of the assignment of initial parameters (settlement of a support, angle of rotation of the bearing section) and the length of the cantilever beam have been got. The influence of distribution of flexometers on the cantilever beam and their characteristics on the accuracy of determining the support moment which improves in the course of transition from the uniform distribution of flexometers to optimal non-uniform distribution is shown. On the basis of the inverse tasks theory the method of transformation reduction at numerical differentiation of flexure functions has been studied. For engineering calculation the formulas of error estimate for determining the support moment of the cantilever beam at predetermined errors of flexometers have been obtained.
    Key words: cantilever beam, support moment, cross bending, inverse task, numerical differentiation, approximation, error, flexometers.

    Abstract. The problem of free oscillations of elastic orthotropic plates with homogeneous and combined boundary conditions is considered. To determine the natural frequencies of such structures it is proposed to use the method of interpolation on factor of the form based on the similarity of the integral of geometric characteristics of the form of the plate and its physical and mechanical properties. Analytical expressions for calculating frequencies of own oscillations of elastic orthotropic plates of basic forms are presented. These expressions can be used for selecting support solutions according to this method. In addition to the shape factor, ratios of the cylindrical rigidity along the coordinate axes of the plates are introduced as arguments of analytical expressions. An example of the solution of the problem of free oscillations of orthotropic trapezoidal plate with help of this method is shown.
    Key words: orthotropic plates, free oscillation, shape factor, ratio of cylindrical rigidities, natural frequency of oscillation, interpolation technique by shape factor.

    Abstract. The interconnection of the fundamental frequency of free transverse vibrations of cross- beams systems (with different cell sizes on the rectangular plan) and their maximum deflections under the action of evenly spread load depending on the stiffness characteristics of nodal connections is considered. Frequencies of own transverse fluctuations of cross-beams systems on the rectangular plan at various side ratios as well as maximum deflections of systems under the evenly spread static load are calculated with the help of the numerical method. Coefficients determining the interconnection of frequencies of own fluctuations and maximum deflections have been obtained. Dependences of deflections and frequencies of cross fluctuations depending on rigidity of nodal connections and the size of cells for systems of cross-beams on the rectangular plan with various side ratios are constructed. It is shown that with reduction of the sizes of cells the coefficient obtained tends to the similar coefficient for plates with a similar ratio of sides regardless of the flexibility of nodal connections.
    Key words: cross-beams system, stiffness of nodal connections, own flactuation frequency, maximum deflection, rectangular systems, ratio of sides.

    Abstract. Achievement of sustainable development in Russia today is impossible without stability in the development of separate administrative-territorial units, in particular cities. This process also requires significant financial expenses. One of the main sources of financing is the funds of investors.The investment potential of the city is considered as an instrument of attracting investment resources needed for the development of municipal facilities, a basic component of the city system. The model of analysis and forecasting of investment potential of the city with the use of the theory of optimum design, leaning on the system of four individual potentials - financial and economic, innovative, infrastructure and savings - with a view of improving the efficiency of management of investment capacity of the city for achieving its sustainable development has been built. Calculations are based on data for regional centers of Central Black Earth Economic Region - Kursk, Belgorod, Tambov.
    Key words: city development, investment management, investment potential, sustainable development.

    Abstract. To understand the operation of the steel structure it is always important to explore ways of calculating the residual stresses, since these stresses can have a negative effect on strength. In the course of analyzing the known calculation methods, it was concluded that the problem of finding the residual stresses from welding splits into two parts. In the first part, the temporary stresses or plastic deformations are determined, in the second part - the residual stresses from welding. For solving the second part of the task it is necessary to know the size of the zone of plasticity spreading. For finding the maximum width of the field of development of plastic deformations it is proposed to define the intensity of the temporary stresses and compare them with the yield strength of steel. The plane stress state and plane source of heat are considered. For derivation of formulas the method of "fictitious temperature" of prof. V. S. Ignatieva was used. The theoretical results obtained are consistent with the experimental ones taken from periodicals. It is concluded that the temperature of the weld, corresponding to the maximum development of plastic stresses (deformations) and the sizes of the plasticity zone depend on physical characteristics of a particular class of steel. The dimensions of the area of the development of plastic deformations significantly influence on the determination of actual bearing capacity of welded steel structure.
    Key words: residual welding stresses, temporary stresses, region of development of plastic deformations, load-bearing capacity, welded steel construction.

    Abstract. The architectural-structural solution for pre-fabricated residential and public buildings with an internal supporting framework of reinforced concrete frame-panels designed with a preset level of structural safety is proposed. Cost of buildings of proposed type is by 20-25 % lower than in a brick variant. Total labor costs for their construction are lower by 30 % at least, construction time is reduced in 1.5-2 times. The results of experimental and theoretical studies on the development of the theory of structural safety of buildings bearing systems under design and beyond- design actions are presented; they show that the sudden application of beyond-design load to the loaded statically indefinable system causes the dynamic loading of all elements of the system.
    Key words: structural system, residential and public buildings, structural safety.

    Abstract. Methods of the checking calculation of the phase-changing heat accumulator under the terms of charging with the use of the quasi-stationary model of its heat condition are presented. The problem of determining the time of complete meltdown of heat-accumulating material during its warming has been solved. The dependence of the dimensionless time of a heat accumulating cell charging with preset parameters on the input temperature of the warming heat carrier is illustrated with a numerical example. The developed instrument makes it possible to analyze the significance of the impact of various factors on the accumulator charging process and to design phase-changing heat accumulators with preset structural and technological characteristics. The engineering methodology of calculation offered makes it possible to more efficiently solve the problems of practical realization of energy and resource saving technologies. The inclusion of such type devices into heat supply systems of buildings and facilities can increase the level of living comfort and reduce the heat consumption.

    Abstract. Important issues of ensuring the technical and economic efficiency of the existing development of the city are an integrated development of territory, creation of infrastructure, solving social and economic problems, the choice of organizational forms of management of objects of renewal, distribution of risks between the city and the general developer (development company), determination of financing sources for reconstruction works etc. In this situation, the reconstruction and technical renovation of civil and industrial stocks of major cities acquire great importance, since the current stage of urban development is characterized by an ever increasing rate of updating historical areas of the city. The objects of reconstruction are classified by the nature of planned construction and assembly works and degree of their complexity: easy, complicated and very complicated. This feature should be used for characterizing design decisions on the appropriateness of the reconstruction of the facility or complex, determining conditions of construction and installation works execution and preliminary cost estimates, as well as for selecting organizational forms of professional construction management.
    Key words: urban space, existing development, object of reconstruction, industrial building.

    Abstract. Issues of restoration of bearing capacity of geometrically non-linear shallow shells on the rectangular plan by means of increasing their thickness in the center or in the part near the support are considered. Conditions of durability, limitation on the value of critical load in the shell under the static action of vertically distributed load for different types of resting of its edges are taken into account. As an example, the calculation of an armocement shell on the rectangular plan is presented. The developed algorithm of optimization of thickness distribution along the middle surface as well as the presentation of variables in the dimensionless form makes it possible to use it for the restoration of bearing capacity and operational characteristics of shallow shells of coverings for buildings and structures.
    Key words: geometrical non-linearity, shallow shells, critical loads, stresses in shell, shells of variable form, shells of variable thickness.

    Abstract. Data on changes in characteristics of soils of buildings foundations in the course of operation of which the values of design resistance were exceeded are presented. Empiric formulas making it possible to define the corner of internal friction and specific soil cohesion after the predicted period of time are given. It is shown that the design resistance of the soil increases in direct proportion with the increase in compression ratio which represents the relationship of additional pressure with the initial value of design resistance. In the course of reconstruction of buildings, foundations of which during the long time operated with a high compression ratio, it is necessary to pay the main attention to deformations and cracks appearing as a result of settlements, to conditions of foundation body and main bearing elements.
    Key words: reconstruction of buildings, design of bases, calculated resistance of soil, angle of internal friction, specific adhesion, non-linear inelastic system.

    Abstract. Modeling of a 5-storey residential building (Soviet 105series) before reconstruction and after modernization was conducted with the use of WUFI+ software. Results of the calculation of heat consumption of residential buildings under operation according to the proposed methodology with model values obtained with the help of the WUFI+ software package are compared. The recommended corrected formulae for determining the specific energy consumption for the heating period per 1 m2 of housing determine the energy consumption more reliably. The formulae obtained make it possible to calculate the specific energy consumption for the heating period taking into account the use of recuperators of different efficiency.
    Key words: specific heat consumption, energy efficiency of building, recuperator, correction factors, energy consumption in buildings, thermal insulation of residential buildings.

    Abstract. The distinctive features of electrochemical protection against the corrosion of an heat-insulated pipeline with sections of above-ground laying on the example of the oil pipeline "Zapolyarye-NPS "Purpe" are considered. Technical solutions applied during the construction of the pipeline and the system of its electrochemical protection are described. Issues of concern requiring the increased attention during the operation and diagnostics are specified. The electrochemical protection of heat-insulated pipelines possesses some features which are very important in the presence of sections of above-ground laying. Despite the fact that at the electrochemical protection of heat-insulated piping the set of instruments and the configuration of the system practically does not differ from the standard ones, there are some challenges that require increased attention during the operation and diagnostics of the electrochemical protection system. To avoid undesired effects, it is necessary to exclude the electric contact of the pipeline with supports, that was implemented in the project of the oil pipeline "Zapolyarye-Purpe" with the help of dielectric elements.

    Abstract. Renewable energy sources (RES), which gain increasing importance in the balances of electricity and primary energy, are a component of sustainable development, having certain advantages over the traditional energy (based on fossil fuel - hydrocarbon), namely the absence of emission of greenhouse ("climatic") gases as well as harmful chemical elements on the whole into the atmosphere. At the same time the fossil hydrocarbons, which is not much left on the Earth, are used as raw materials for industry. The "fuel" for RES is "complimentary" natural phenomena: energy of the sun, wind, flowing waters, underground heat and others. However, the use of such RES does not pass without any trace for biosphere. This article is devoted not only to revealing the negative impact of RES on nature, but also to maximal weakening this impact using technical means.

    Abstract. Reducing the consumption of fresh river water is one of the major challenges in the production and economic activity of the sugar plants. A significant role in it plays the circulating water system of cooling water supply. Conditions of the balance scheme of water consumption and water disposal including the reverse cooling water supply are analyzed; weaknesses in the balance scheme of water of the 1st category of the main building are identified. Technical developments which make it possible not only to reduce the water consumption for condensation of secondary steam from vacuum apparatus but reduce capital costs for construction of the recirculated water system and also to reduce operating expenses are proposed.
    Key words: recirculating water supply, cooling towers, cooling, sugar production.

    Abstract. Results of the experimental tests conducted with the purpose of determining the bearing capacity of inclined piles and bending moments in metal tubes in the course of reinforcement of piles are analyzed. It is established that steel tubes of piles operate enough reliably within the maximum loads applied to the pile grating during tests. Taking into account the data on measurement of deformations in pile reinforcement the way of further scientific studies with the purpose of creating the methodology of determining moments appearing in inclined piles in the course of their loading is proposed.
    Key words: static pile test, moment of force, bending moments, field experiment, inclined piles.

    Abstract. The issues of application efficiency of modern digital means of teleinspection with high resolution, making it possible to receive the three-dimensional image of the objects - individual failure sections of the pipeline network - are considered Three-dimensional and scanned images of defects on the inner surface of pipelines make it easier to adopt decisions on localization of damages in favor of the corresponding methods of trenchless renovation. The device and principles of operation of telediagnostics means are presented; comparison of different diagnostic systems of the inner pipeline surface is made.
    Key words: diagnostics, pipelines, defects, repair.
