    Abstract. A non-stationary axisymmetric problem for a rigidly fixed circular laminated plate under the action of distributed load on the end surface (normal stresses) is considered. This load is an arbitrary function of the radial coordinate and time. For definiteness, a three-layer system is studied. New closed solution has been constructed within the theory of elasticity in three-dimensional statement by means of the consistent use of the method of incomplete separation of variables in the form of finite integral transformations. The Hankel transform is applied consistently with finite limits on the axial coordinate and generalized finite transformation (MRA) on the radial variable. At each stage of the solution, the procedure of standardization is conducted that allows implementing the appropriate algorithm of transformation. The calculated ratio makes it possible to study the character of variations of the stress-strain state of the laminated plate and to make the qualitative and quantitative analysis of mechanical stress fields relatedness in composite laminated structures. In addition, it is possible to analyze the impact of structural and mechanical properties of materials, the order of layers, the ratio of thicknesses of layers in the package, as well as their number on self-axisymmetric frequencies and forms of natural oscillations of structures.
    Key words: laminated plate, boundary problem, elastic theory, dynamic load, integral transformation.

    Abstract. Cylindrical shells are widely used in the construction of underground structures. Development of the calculation algorithm of cylindrical shells is a very important problem of the construction science. Generalized equations of the finite difference method is a new trend in the calculation of building structures and make it possible to solve a wide class of engineering problems. The proposed method has high accuracy and can be implemented with a small number of partitions, even without the use of computers. To solve this problem, an algorithm is constructed: differential equations of the cylindrical shell deformation are approximated with generalized equations of finite difference method, approximation of the boundary conditions is performed. The resulting system of equations is solved together with the involvement of the iterative Gauss-Seidel method. By using the developed algorithm, the engineering problem of designing the concrete cylindrical shell loaded with cyclically applied load is solved. The values of transverse forces, moments, and deflections in different sections of the shell have been obtained; a convergence of the solution is shown. Results of the solution are compared with the known analytical solution.
    Key words: finite difference method, method of successive approximations, cylindrical shell, calculation algorithm, finite element method, generalized equations, building construction.

    Abstract. An experience in the calculation of structures of a two-story industrial prefab building assembled from block-boxes is presented. The design of a building model in the computer systems is described. Peculiarities of the design model and load summary are presented. The special features of the design diagram include: accounting of joint operation of horizontal frames, misalignment of joint connections, and roofing deck operation. When collecting wind loads on the frame, special attention is paid to the definition of the natural vibration frequencies of the building as well as the contribution of the fluctuating component of the wind load. It is established that the fluctuation component makes a significant contribution to the total wind load. The main results of the building structures calculation of the prefab building are given. On the basis of performed calculations, elements and joint connections that do not meet the conditions of strength and stability have been identified. Methods for strengthening, which make it possible to bring the building to the workable state, are offered for these elements and units. In conclusion, the main directions of development and study of prefab buildings are formulated, they are the research and development of block-boxes joint connections and research in the operation of multi-storey modular buildings under the impact of dynamic loads.

    Abstract. Results of the study of oscillation impact of separate parts of the Zhiguli Hydroelectric Station on the building structure as a whole are considered. The vibration loads on the various elements of the power house, which can cause damage to the building structure, thereby reducing the operational reliability of the entire structure and bring potential harm to the environment and human life support, are analyzed. The need for vibration control of structures which should be carried out continuously or periodically to determine the current state of framework is substantiated. The oscillations of the concrete parts of the section and hydraulic units of the Zhiguli Hydroelectric Station are considered; for detecting the oscillatory motion of the section as a rigid body on the elastic foundation, one of the sections was selected. The data about registration of vibrations, which were conducted in all three components: vertical, horizontal, parallel to the flow, and perpendicular to the flow, are presented Intervals of observed and dominant periods of oscillation are estimated. According to the studies data, the amplitudes and accelerations of oscillation as well as the data on the maximum registered scopes have been established. On the basis of vibro-records obtained, it is stated that registered oscillations are non-periodical, but they have a relatively narrow range of periods. It is concluded that in order to establish the maximum possible oscillation amplitudes of the section and, also to calculate the corresponding dynamic stresses in the girders, it is necessary to conduct the vibration monitoring with simultaneous operation of hydraulic units and pass flow through the fully open bottom spillways of the study section.
    Key words: Zhiguli Hydroelectric Station, vibration control, oscillation registration, oscillation amplitude, acceleration of fluctuations; maximum registered scope, histogram.

    Abstract. The article deals with the probability of destruction of a five-story section of a residential building at the beginning of destruction from any floor and at destruction of floor slabs only. The floor slabs are presented as precast concrete slabs with round voids. Methods of the collection of statistic data about technical conditions of building structures in the operated building are presented on the example of reliability evaluation of the residential building. Calculation of reliability of elements was conducted on the basis of the composition of distributions of real load on the structure and breaking load. In order to take effective measures to reduce the emergency risk, it is necessary to get objective data about the structural condition of objects. Main positions of the reliability calculation of structures as systems are presented. The system is defined as a great number of interrelated and connected units, which form a certain entity and unity. The feature of these systems is the presence in their structure of elements and their interrelations. The possibility of failures was identified with the help of multiple integration method and the package of application programs Mathcad. These programs are written in QBasic language. Integration was carried out with the help of Simpson method. The calculation results made it possible to formulate the regression equations.
    Key words: distribution load, bearing capacity, construction, reliability, residential building, concrete slabs, dynamic loads, failed state, liquid limit, strength, deformation.

    Abstract. The use of I-beams with parallel sides of flanges is very efficient in columns of building metal frameworks. The purpose of this article is to consider steels for these profiles corresponding to the modern possibilities of the metallurgical industry. The analysis of using such profiles in construction shows that there are significant limitations on the thickness (up to 40 mm) of rolled metal, depending on its strength, due to existing standards that are now obsolete. Increased, over the past 30 years, possibilities of the metallurgical industry make it possible to supply the structural steel of much higher quality to builders. For high strength structural steel, manganese-silicon steels with manganese content of 1.3-1.7% and silica of not more than 0.8% are used; efficient alternative steels, the use of which is directed toward the import substitution of manganese, reserves of which are limited in our country, is considered. High purity of present steels concerning harmful impurities makes it possible to significantly improve the cold-resistance of profiles and to put forward high requirements concerning impact toughness for specimens with sharp notch. Properties of used in our country wide flange column profiles with the flange thickness of up to 140 mm with high strength and cold-resistance are presented. It is concluded that the use of profiles with high operation properties based on achievements of the modern metallurgy is possible in construction.
    Key words: steel structures, columns, I-beam with parallel sides of flanges, improved and high strength, steels for shape steel-roll stock, alternative steel grades.

    Abstract. The procedure of the study of brick piers strength reinforced with sheets of carbon-fiber fabric under the action of static shearing load (effect of distortion) is outlined. It simulates the seismic impact on stone structures during earthquakes, results of the study are analyzed. Variants of reinforcement of brick piers with sheets of carbon-fiber fabric with one or two-sided arrangement of elements are considered. The comparison with the results of test for misalignment of non-reinforced brick piers is made. The technique of fixing sheets to the brick masonry is described. An empiric dependence for determining the bearing capacity of brick piers with due regard for the character of their reinforcement with carbon fiber against the action of shearing force is proposed. Reinforcement of brick walls of buildings with the carbon-fiber fabric according to proposed structural schemes makes it possible to improve their bearing capacity at the joint action of horizontal and vertical static loads (misalignment). The bearing capacity of wall samples at one-side strengthening increases, at misalignment, by 1.48 times, at two-side strengthening - by 1.92 times. Good coincidence of the calculation results according to the proposed formula with the experiment data is noted.
    Key words: carbon-fiber fabric, shearing load, brick piers (partitions), deviation misalignment, reinforcement.

    Abstract. The national project "Affordable and Comfortable Housing - to the Russian Citizens" is designated by the president as a major nation-wide task. The solution of this problem is possible with the use of rolled and bent-welded profiles in construction of low-rise residential buildings. The article presents a comparative efficiency analysis of the design and construction of low-rise housing using steel rolled profiles and lightweight thin-walled structures (LSTK) in the climatic conditions of Russia. As for assembling terms, the frameworks of steel rolled profiles do not concede the frames of LSTK frameworks, and taking into account their durability, materials consumption and possibility to use large-size panels (characterized by small amount of non-uniformities and joints) for walling - are even more effective. Considering production capacities of the Russian manufacturers of rolled metal and the necessity to provide affordable and high-quality housing, the construction of low-rise residential buildings using rolled, bent-welded and bent profiles is a matter of topical interest.
    Key words: framed buildings, steel lightweight thin-walled structures, steel rolled profiles, durability, enclosing structures, cold bridges.

    Abstract. The general requirements for thermal insulation products including fire-safety have been considered. It is established that materials obtained on the basis of liquid glass, which is capable to swell significantly during the heat treatment, are of big interest. Results of the research in developing compositions and technologies of producing highly porous silicate insulation products of wide application conducted in the Samara State University of Architecture and Civil Engineering are presented. This technology is based on the results of studies of modified liquid glass swelling and receiving on its base porous granules and a light-weight powder filler. To ensure the homogeneity of products structure, an innovative technology of two-stage structuring, which makes it possible to obtain a uniform fine pore structure, is offered. The obtained test results of insulation products based on the developed technology show high thermal insulation properties of the product. Additionally, these products have high heat and fire resistances that allow them to be recommended for insulation of "hot" equipment, industrial pipelines for example.
    Key words: insulating products, modified liquid glass, swelling, porous granules, molding, non-combustibility, fire resistance.

    Abstract. The article is devoted to the problem of formation of great amounts of construction waste both during the construction of new objects and in the course of dismantling of buildings unfit for further use. In this regard, the development of methods for the secondary use of building waste is a very actual problem. The article considers the issue of formation of a great volume of construction waste which is not practically reused. The analyses of construction sites revealed that crushed concrete, which has different strength and other characteristics, constitutes the major part of waste. Results of the laboratory study carried out to determine the characteristics of secondary broken stone got from crushed concrete are presented. Comparative analysis of the resulted material and the material quarried in the Middle Volga Region area shows their identity. The paper evaluates the possibility of using the secondary crushed concrete when building and reconstructing the elements of hydrotechnical objects; the recommendations for improving the quality of building materials are given. Techno-economic evaluation of the cost of broken concrete recycling shows the feasibility and competiveness of recycling and reuse of these waste.
    Key words: construction waste, broken concrete, secondary crushed stone, strength characteristics, hydraulic facilities.

    Abstract. Industrial waste is a real threat to environmental safety. In this regard, the problem of recycling both of newly formed and already accumulated waste is a topical one. The aim of this work is to determine the possibility of using the certain types of industrial wastes in the production of building materials as a complete anthropogenic raw material. Sludge formed by chemical precipitation in the course of industrial wastewater treatment is considered from this point of view. It is emphasized that the conditions of sludge formation fit into the concept of sol-gel nanotechnology. Over atomic structural parameters of sludge (particle size distribution, fractal dimension) have been defined by small-angle neutron scattering. This makes it possible to classify the sludge as a nano-anthropogenic raw material and it points to the need to take into account nano-technological aspects of their use of in the production of building materials.
    Key words: industrial waste, anthropogenic raw materials, sludge, nano-materials, nano-modifiers, small angle neutron scattering, fractal dimension.

    Abstract. Increase of requirements to quality of building products and materials, as well as to reducing the energy consumption for their production requires the development of new methods for automation of processes for the production of concrete and ceramic products. The main technological features of concrete products and ceramic materials production as objects of automation have been considered. It is shown that they are objects with distributed parameters either because of significant geometrical product sizes, either because of distribution of technology implementation in time and space. In addition, these objects are characterized by their nonstationarity, pronounced cross-connections, nonlinearities caused by production technology and structural features of construction enterprises equipment. The requirements to the automatic control systems of concrete products and ceramic materials production have been stated. As the study shows, the use of the structure with artificial intellect elements is the most rational for ensuring the efficient production of these products and materials with specified levels of quality.
    Key words: concrete products, ceramic materials, management systems, automation object, energy efficiency, intelligent management.

    Abstract. Increasing volumes of passenger transportation by air, make topical the technological design, construction, reconstruction and re-equipment of expanding airport terminals for domestic and international flights of civil aviation of the Russian Federation. The evolution of planning solutions and methods for optimization of technological processes of a passenger terminal taking into account normative requirements for the design, construction and operation of airport terminal complexes and checkpoints are a base for development. The article considers the urban planning requirements for the modernization of the Russian Federation airport network in the context of the unified system of settlement and formation of cities. The complex of architectural-town planning measures to develop the airport network in the context of the unified town planning settlement system in the structure of united cities-associations is proposed. The ways to include the complex of airport buildings into the transport hub united with the single multimodal transport network of civil transportation and ensuring the "seamless" implementation of various technological and operational processes are shown. The schemes of interrelation of the urban planning formation of airport terminals with residential clusters through the multimodal transport hub are considered.
    Key words: airport complex, multimodal transportation hub, seamless integration, optimization of technological processes.
