    Abstract. The article deals with the issues of location of railways and motor roads across water bodies on water- retaining structures of high-head water power developments, erected in Russia and abroad. The author analyses conditions of motorways arrangement on the crests of arch and arch-gravity dams and modern problems of their operation. The analysis shows the major importance of such roads for regions, which is reflected in their important role in development of natural-anthropogenic objects and recreational zones that are very attractive for tourists. The article also highlights peculiarities of constructive solutions concerning configuration of transport junctions on mass concrete dams. As examples, high-head water power developments constructed in Russia on the Yenisei and Angara rivers are given. The paper also provides analysis of factors that influence on the decision-making process concerning road furnishing and their parameters. The author concludes that the type and constructive parameters of retaining structures, topographic and geological conditions of the region as well as formed characteristics of transport network and its role in region development are mostly valuable for reasoning the parameters of transport crossings across rivers on high-pressure concrete dams.
    Key words: high-head power development, concrete dam, dam crest, transport link, motor junction.

    Abstract. Numerical studies of the stress-strain operation of a steel column are conducted. The purpose of research is to specify the work of the column base of a simplified type under the eccentric compression, to determine numerical characteristics of the elastic reaction of the column base to force action. The goal was achieved by solving a number of problems with the variation of thickness of the base plate of the computational model which was created and calculated by means of SolidWorks/CosmosWorks. Deformations graphics of specific part of the column base have been constructed. The controlled specific parts of the column base were the edges of the base plate; the edges of the column shaft adjacent to the base plate; the upper end surface of the column shaft. It is established that the deformation of elements constituting the column base has a similar dependence on the thickness of the base plate for various controlled parts. It is defined that the deformation diagram of the support plate of the column base of a simplified type has three characteristic parts: the zone of elastic (hard) work, flexible working area (geometrically nonlinear operation), the area of geometrically and physically non-linear operation. It is noted that the nature of deformation of the column base studied can be divided into three types: "hard stamp", "flexible plate" and "ultra-thin plate". For the thickness of the base plate starting from 70 mm, the practically linear deformation of the base is typical, for the thickness from 20 mm to 70 mm - non-linear elastic deformation. When the thickness of the base plate is up to 20 mm, the non-linear deformation with manifestation of plasticity is observed.
    Key words: finite rigidity, steel column base, base plate, elastic non-linear deformation, linear deformation, plastic deformations, physical model, design model.

    Abstract. The paper considers the design data and features of the monolithic slab design on the profiled steel decking, which is used as a permanent form when the slab is concreted and also functions as its outer principal reinforcement at the stage of floor operation. The profiled decking is made with the use of sheet cold-bent profiles with trapezoidal corrugations, on the walls of which there are blankings in the form of regularly located dents and cambers (reefs), providing the bond between the decking and concrete of slabs. The continuously galvanized sheet steel is selected as a material of decking profiles. To improve the efficiency of decking operation as a principal reinforcement of the slab, at the ends of decking, the anchoring supports or vertical steel bars (called "pitch pin anchors") welded to the floor beams through the decking are installed. The slab design consists of two steps: design of decking during placing of concrete into the slab and design of a reinforced concrete slab with principal reinforcement of profiled decking and anchoring supports on support beams. Strength and deflection of the decking at the stage of slab concreting are calculated at the transverse bending as for a thin-walled steel construction according to Eurocode 3. At the stage of the composite floor operation, the reinforced-concrete slab is calculated using the first and second limit states. In addition, the strength calculation for normal and oblique sections, test of the bond strength between decking and concrete, assessment of the anchoring supports deformation capacity and calculation of slab deflection under the design load are made. The use of improved methodology of calculation and design of monolithic reinforced concrete slabs on the profiled steel decking will favor the introduction of these structures into the building practice.
    Key words: monolithic reinforced-concrete slab, profiled decking, permanent form, principal reinforcement, bond between deck and concrete, limit state design.

    Abstract. The paper proves that for producing the uniform structure bricks with specified durability and with minimum deviation from their geometrical shape, it is necessary to automatically control the process of ceramic mixture molding in a vacuum screw press. It is a ceramic mixture shearing rate in the outlet molding section that should be specially controlled. The practical solution of this problem is not easy to find because, firstly, there is no direct interdependence between the bricks strength and the shear rate since the technological process of molding is multi-factorial and non-stationary. Secondly, there are no special devices able to measure the rate of ceramic mixture shearing strains in the outlet molding section of the press. The paper shows that in order to achieve this purpose it is necessary to use mathematical models of the molding process in certain spaces. The coordinates of these spaces are target value of bricks strength and technological molding parameters: humidity and ceramic mixture flow index, screw angular speed, depression in the vacuum chamber. The authors introduce an algorithm of digital implementation of assigned stress generator and shearing rate observer. The algorithm takes into account technological restrictions in brick production. The use of developed digital devices makes it possible to stabilize the production of bricks with assigned strength characteristics, at the same time reducing the energy costs and increasing the molding efficiency.
    Key words: ceramic brick, vacuum screw press, molding, ceramic mixture shearing rate, mathematical modeling, screw gear, brick strength, shearing rate observer.

    Abstract. The paper describes some structural peculiarities of three-layer-sandwich panels with the middle layer of basalt wool: fiber structure of basalt insulation makes it possible to consider it as a material with orthotropic properties; the middle layer in the panel design is cut for pockets which are glued only to sheetings and not glued with each other; elements of the corrugation are filled with the insulant with horizontal orientation of fibres and are not glued to the main mass of the middle layer; bottom sheeting is flat, upper sheeting is corrugated. The calculated model with these structural peculiarities has been developed with ANSYS software system with due regard for orthotropic properties of the middle layer. The volumetric stress-strain state of three-layer roofing panels is proposed. The comparison of calculation results with the data of experimental studies is made. Their good agreement is noted. Stresses in glued connection of three-layer panels are determined. On the basis of conducted calculations and comparison of results with experimental data, it is established that the compression of the middle layer and rigidity of insulation strongly influence on the value of deflection. The proposed calculated model with due regard for orthotropic properties of the material makes it possible to take into account the convergence of layers of the middle layer under loading. On the basis of the kinetic concept of solid body destruction, the service life of the glued connection and mineral wool plate is calculated with due regard for external factors impact and temperature.
    Key words: orthotropic middle layer, three-layer roofing panel, calculation of three-layer panels, panel durability.

    Abstract. The influence of tangential stresses on the nature of stress-strain state of the material due to the presence of friction forces (shear stresses) on the contact surfaces is considered. Since the value of tangential stresses is large enough, then their change significantly affect the nature of the stress-strain state of the material. It is absolutely necessary to radically reduce shear stresses so that the working conditions of bended and compressed construction elements are identical to the test conditions. The calculation confirms that the surfaces, where the largest linear deformations take place, are the fracture surfaces. It is recommended, firstly, in the manufacture of concrete to use smaller fillers to avoid the abrasive effect on surfaces of the contact, secondly, to minimize the influence of shear stresses at the ends of the sample as a result of application of the lubricant layer. Contradictions in the calculation of concrete classes according to the dependencies recommended in normative documents are determined.

    Abstract. The influence of natural zeolite additives on the physical-chemical properties of concretes has been studied. The complex of electrical properties (conductivity, dielectric constant, dielectric loss tangent, electrical breakdown) of concrete with mineral zeolite additives as inorganic solid dielectrics in the temperature range of 20-160 C has been investigated. Zeolite tuffs of Kulikovo Deposit, Amur Oblast, were used as natural zeolites. It is established experimentally that in the course of concrete samples heating, the specific resistivity initially decreases, then, reaching a minimum, begins to increase. The dielectric constant and dielectric loss tangent of the samples decrease linearly with increasing temperature. At temperatures of about 150C thermal electrical breakdown is observed. Experiments show that zeolite additives do not impair the electrical properties of concrete. In addition, it is revealed that the content of zeolites in the composite binder improves the parameters of the concrete mix. At that, the degree of cement hydration at early age increases, the porosity of cement stone decreases, the density of binder also decreases. As a result, the cement consumption is reduced without significant reduction in the strength of concrete.
    Key words: concrete, zeolite, composite binder, dielectric, polarization, resistivity, dielectric constant, dielectric loss tangent, electrical breakdown.

    Abstract. Problems of applying of copper manufacturing waste as a fine grinding active mineral admixture for production of concrete are considered. The strength gain dynamics of concrete with addition of anthropogenic waste of non-ferrous metallurgy is studied. This trend is relevant for today's science because of growing rates and scales of construction. When executing concrete works, the use of new complex admixtures on the basis of industrial waste is an important factor of their effectiveness. By present time, copper slag dumps located in Ural Federal District haven't been widely used in construction or in other industrial production. The correct utilization of copper-smelting production waste will helps to solve ecological problems of regions of Russia. Results of the study of strength gain dynamic of concrete with the use of fine grinding slag of copper smelting show that active chemical reactions of the mineral additive with Portland cement positively impact on the strength characteristics of concrete. The article graphically presents the process of strength gain of concrete with the fine-grinding additive and results of the test of investigated samples of concrete for axial compression and bending. The data obtained confirm the reasonability of using this type of industrial waste.
    Key words: cooper slag, utilization of anthropogenic waste, fine grinding mineral admixture, concrete with anthropogenic waste, mixed binders.

    Abstract. A real process of the urban development cycle of production facilities, in particular the public housing, has not been systematically analyzed In Russian and foreign practice. This research considers urban development process as a set of interrelated stages of design and construction. A normative model of urban cycle using the generated database of real public housing objects of capital construction budget was developed and the practical models were explored for the groups of objects in 2013-2014. Urban development process modeling allows to construct eighty two public housing objects and fifty nine objects that belong to Moscow Department of Education. Each object identifies critical (essential) retreat (inconsistency) from standard models of urban development process that allows to form statistical evidence identifying the main trends and possible causal relationships of deviations between normative and the actual duration of the stages, which leads to delays in the overall time of urban cycle and increases period between starting and settlement.
    Key words: model of the practical urban development process, the normative model of residential facilities construction and costs distribution, urban development cycle time.

    Abstract. The evolution of architectural and design decisions of production buildings of industrial enterprises in Central Russia in the early twentieth century, built in Art Nouveau style, are considered. It is shown that the industrial architecture of that time and style abandoned the tradition of construction of industrial red-brick buildings with massive walls in the spirit of provincial classicism and in the so-called "brick style". As a result of active involvement of domestic professional architects and civil engineers in the design process of industrial buildings, some structures built in the tradition of early and then late Art Nouveau, have received highly artistic decisions. Appeared in this period, the elements of new typological systems of natural lighting of buildings, fire fighting, and engineering system of air conditioning have enriched the palette of architectural forms of industrial buildings. Despite the continued widespread use of red brick, the architecture of the period under consideration ever more perceived the new tectonics adequately reacting to the introduction of the timber frame structural system in the construction. Simultaneously, the expansion of the field of reinforced concrete application in industrial construction, it is in the Art Nouveau epoch, has inevitably led to the emergence of a completely different architecture-art system encouraged to reflect the aesthetic properties of the new material. It is noted that some echoes of Art Nouveau in the industrial construction of the region was observed until 1927, when the constructivism style fully declared itself. The article provides the description and evaluation of valuable features of production buildings and facilities, which are the basis for their recognition as cultural heritage objects.
    Key words: industrial architecture, Central Russia, early Art Nouveau, late Art Nouveau, cultural heritage objects.

    Absatrct. The article deals with preconditions for the yachting development in Russia and, in particular, the possibility of forming the construction base of harbors and world-class marinas in Crimea. It is noted that when organizing the objects of water-sailing and rest, it is very important to take into account the advanced experience of countries where this type of leisure has been developed. At present, such facilities in Russia are underdeveloped and don't meet modern requirements. The article gives the professional terminology adopted at designing, construction, and international communication. Requirements for the territory organization are considered, and the choice of the marinas location is shown on the example of the United Kingdom. It is also exposed how the UK yacht harbors and marinas have been formed in the past and how they are organized today. The necessity of creating in Russia a modern regulatory framework and the basis for the design of yachting service facilities is noted. Construction of these facilities contributes to the development of tourism and sport, and creates new jobs for the local population as well as conditions for developing these regions.

    Abstract. The organizational structural integrated model of reproduction processes in housing construction is offered. It is shown that the strategic direction of the solution of priority problems of sustainable economic development is the innovative strategy connected with power - resource-saving and greening. Against the low competitiveness of the enterprises of domestic building industry, high power consumption, and resource dependence of construction products only the introduction of resource- energy saving technologies at all stages of the life cycle of objects of residential real estate makes it possible to solve the problem of providing the population with affordable and comfortable housing. In turn, the globalization of environmental problems, the need to create the safe living environment of citizens demand the development of innovative sector of eco-residential real estate on the basis of technologies of "green" building. The generalized models of interactions of enterprises of the construction industry and territories of the region, as well as the participants of investment and construction complex in the course of construction of eco-real estate facilities and introduction of power-resource-saving technologies are offered. The conceptual economic-mathematical model of productive development of housing construction at the territorial and regional level as the multiple-factor function has been developed. It includes the efficiency of using the resource and innovative potential of the region, the productivity of organizational- economic system, and the reliability of the flow-line production.
    Key words: energy saving, resource saving, greening, eco-real estate, "green" building, eco-housing, eco-sustainable project.

    Abstract. The research is focused on solving problems in the construction of buildings, structures and utilities in areas with poor soils. It is shown that the main cause of accidents and strains of buildings existing or under construction is the presence of weak soils and soils with specific adverse properties at the base. In many cases, the cause of additional sediments of soils of structure bases is the unjustified use of construction technologies using the machinery with vibration and shock effect (piling machines, powerful excavating machines, vibrating rollers, etc.). The authors investigated and then proposed technologies for ensuring the strength and durability of buildings through the use of compacted sand base. It was found that for constructing the compacted sand cushion under changing climatic conditions, it is better to use sands of large and medium size. Under difficult soil conditions for ensuring the compaction of sand bases, the scientific-technical support of processes of design and construction of such structures is necessary.
    Key words: artificial compacted bases, soft soil, vibration impact, sand bases, sands of large and medium sizes.

    Abstract. To provide regulatory requirements for fire resistance, the innovative solutions of fire retardant treatment for bearing steel and reinforced concrete structures are considered. The harmonization of the experimental methods for the evaluation of fire retardant effectiveness for the fire protection of steel structures according to the current European standards is analyzed. It is proposed to use the temperature regime of hydrocarbons combustion for evaluating the fire-retardant effectiveness of fire protection means of the oil-gas and petrochemical complexes. The principles of choice of fire protection for steel structures with the help of the structural- methodological scheme are stated in detail. Separately, the issue of protection of lining blocks for tunnel collectors against the brittle (explosive) concrete destruction during fire is considered. Experimental investigations of the fire resistance of these blocks are conducted. The test results make it possible to establish the type and amount of the propylene-fiber additive for reducing the probability of brittle failure of concrete in reinforced c oncrete structures. Introduction of these fibers into the concrete mix for replacing fire protective coatings of reinforced concrete structures can significantly reduce the cost of construction of tunnel structures.
    Key words: fire resistance, fire-retardant effectiveness, standard temperature condition, protection means, standard temperature regime, thermal diffusivity.

    Abstract. Expanded clay production requires heavy energy consumption, mostly when it is burnt in a rotary kiln. Heuristic algorithms of managing the burning process used up to the present day have one main disadvantage: expanded clay burnt in the rotary characterized by the great strength and bulk density spread that leads to cost-inefficient increase in energy consumption. A possible solution to this problem is as follows: to produce expanded clay with stable strength value and, at the same time, to cut energy expenses it is necessary to automatically coordinate expanded clay temperature in three supporting cross-sections of the kiln. The choice of these cross-sections coordinates is aimed at the maximum use of possibilities to control the expanded clay temperature field (within the definite limits) by changing the gas burner and loading conveyer capacities and by changing the kiln rotating speed. The theoretical basis for choosing the position of operating point of synthesized multi-dimensional system of burning control is a reflection of strength properties of expanded clay in the range of various controlled temperature modes. The use of this range makes it possible both to rationally select the complex consisting of three values of temperature modes in supporting cross-sections and analyze the efficiency of these modes in kiln managing.
    Key words: rotary kiln, expanded clay, heat transfer, distributed-parameters controlled object, mathematical modeling, controlled object structure, computational model.

    Abstract. The article presents a new technology of support structures design for equipment using the two-way integration between software products Intergraph SmartPlant3D, TEKLA Structures and SCAD Office v.21. The implementation of this technology is based on the interoperability of these products with the help of open programming interfaces. This approach significantly reduces the labor costs for complex designing, and also reduces the impact of a human factor on the process of re-creating models in various CAD systems, makes it possible to evaluate the situation and eliminate all possible inconsistencies (collisions) before release the documentation. We consider the list of data formats, with which the computing complex SCAD Office v.21 operates. On the basis of this list, you can develop methods for two-way data integration with other software products, that allows a comprehensive approach to the organization of the design process with the use of CAD and CAE systems.
    Key words: Smart3D, TEKLA Structures, SCAD Office, LoadsIMP, communication technology, data formats, collisions.

    Abstract. The paper presents the cost-effectiveness analyses of roof repairs by examining roofs and attics in the 5-storey residential houses. Reasons which caused the formation of icing on the roof rafters are described. It is established that when repairing old buildings being under operation over 50 years, obsolete materials, asbestos-cement corrugated roof sheets in particular, are replaced, are replaced by modern profiled metal sheets without due regard for the whole complex of violations of temperature-humidity conditions of in the attic. Furthermore, the replacement of one waterproof roofing layer for another one without considering the differences in the technologies of roof construction out of materials with different thermo-technical properties leads to the deterioration of operation of the existing bearing structures of the roof. It is concluded that in the course of planning of the overhaul, for improving its efficiency, it is necessary to provide structural solutions, which improve the roof operating characteristics, and the use of up-to-date developments.
    Key words: roof, vapor barrier, overhaul, temperature-humidity conditions, roofing, metal profiled sheet.
