    Abstract. Despite the difficulties, the development of the Arctic areas of Russia continues. Participating in the project Novatek "Yamal LPG" in 2014-2015, the Research Institute of Concrete and Reinforced Concrete named after A. A. Gvozdev controlled the quality of manufactured concrete and operatively solved the problems under conditions of emergency situations. The use of the sliding formwork of "Gleitbau" Company made it possible to construct walls of four reinforced concrete LPG tanks during the relatively short period of time despite the harsh conditions of the Arctic. Experience of specialists of the institute confirms the need for performing the complex scientific-technical support of all construction and installation works and monitoring unique, remote and especially dangerous objects constructed under conditions of the Extreme North. Timely detection of technological causes for formation of cracks in critical structures, including pre-stressed, is a main task of scientific-technical support that makes it possible to reduce non-production expenditures for correction of identified defects, improve the reliability and safety of the object constructed.
    Key words: reinforced concrete, high-strength concrete, prestressed concrete, cryogen reinforcement, reservoir, liquid gas, Yamal, scientific-technical support.

    Abstract. The problem of accumulation of industrial waste, which occupy vast areas of lands (including fertile) and adversely affect the environment, makes more urgent the development of technologies of using the waste as a raw material for production of building material. Results of the study of multi-layer external walls in housing construction with the use of multi-component cement and cementless foam concretes with low density and thermal conductivity are presented. The technology providing for the preparation, directly at the construction site, of foam concrete, basic components of which, along with the cement, may be a variety of thin dispersed industrial waste activated preliminary in a liquid medium, is presented. Results of the study show the possibility to obtain thermal insulation foam concretes with high operational properties by using such industrial waste as the thermal power plant's ash, nepheline slags, dust from production of expanded clay gravel, slags, asbestite, etc. To activate multi-component compositions in the liquid medium and produce highly homogeneous thermal insulating foam concretes with a fine-pored structure, special activator-mixers on the basis of rotor-pulsation devices are used. The preliminary activation of industrial waste in the liquid medium makes it possible to produce heat insulating foam concretes of quick hardening, durability of which, unlike the used heat insulators, correspond to the durability of main bearing structures of buildings.
    Key words: multi-layer external walls, heat-insulating monolithic foam concrete, industrial waste, strength, shrinkage, activation in liquid medium, activator-mixer.

    Abstract. When calculating the moisture content of enclosing structures, it is necessary to take into account simultaneously the impact of atmospheric precipitation and wind or slanting rain on the external surface of an enclosing. With the help of a computer program TM&SS, comparative calculations of unsteady temperature-humidity fields for a gas-silicate wall panel of the operating building during the three-year period of time with taking or without taking into account the influence of slanting rains have been made. It is established that the average values of moisture content of the gas-silicate layer of panel changing in time which are calculated with due regard for the slanting rain, are several times larger than the average moisture content without due regard for rain. To verify the results of the calculations for spaced time intervals, the full-scale experiment was carried out. On the basis of statistic characteristics of the random value (moisture content) measured, it was found that average calculation values of moisture content of individual layers and a whole gas-silicate layer of the panel accurately match the experimental data. The computer program TM&SS can be used for design of enclosing structures to predict their moisture content.
    Key words: slanting rain, enclosing constructions, gas silicate, moisture content, capillary moisture transfer, water absorption coefficient.

    Abstract. Various options of the use of non-metallic composite reinforcement in concrete and reinforced concrete structures are considered. Main directions of the development of the theory of analysis of structures with composite reinforcement are formulated. It is shown that the main factor ensuring the reliability is composite rod reinforcement- to-concrete bond. Physical-mechanical characteristics of rod glass-composite and basalt-composite reinforcements such as tensile ultimate strength and modulus of elasticity in tension are presented. Various methods for strengthening reinforced concrete constructions of buildings and structures with composite reinforcement are analyzed. The actual directions of research in the theory of force resistance of strengthened reinforced concrete structures are determined. It is noted that the structure of reinforcing bars significantly influences on the tensile strength and modulus of elasticity. The impact of reinforcing bar diameters from 5 up to 10 mm on their tensile strength which, in some cases, reduces by 35% has been established. It is proposed to carry out the study of the dependence of tensile strength and modulus of elasticity in tension on the bar diameters for the whole nomenclature of composite reinforcement.
    Key words: composite reinforcement, test methods, resistance, bond, relative elongation.

    Abstract. An accelerated method for the study of corrosion resistance of steel reinforcement in reinforced concrete according to the standard NT Build 356 (Norway) based on the measurement of intensity of current flowing through concrete samples is considered. This method is quite simple, easy to perform, takes a relatively short time; its results have high precision and reflect the true nature of corrosion of reinforced concrete structures operated under ground, in water and other corrosive media. On the basis of the results obtained with the help of this method, it is possible to draw evaluation conclusions about the durability of operation of reinforced concrete structures in corrosion-active media. Results of the conducted study show that the high quality fine concrete significantly reduces the rate of steel reinforcement corrosion, stronger hinders the diffusion of chloride ions to the surface of reinforcing rods than conventional unplasticized fine concrete due to the more dense concrete structure.

    Abstract. Problems of the use of composite mesh on the basis of basalt fiber in construction practice are analyzed. Its advantages in comparison with meshes on the basis of carbon glass fiber are pointed. Results of the experimental study of masonry strength from ceramic large-size stone with porosity of up to 54% reinforced with the mesh on the basis of basalt fiber with the use of external reinforcement system "ECOSTROY-BIRSS" are presented. Strength characteristics of the mesh on the basis of basalt fiber of "ECOSTROY" brand and the repair mix "BIRSS RSK" are presented. It is noted that the use of this system of external reinforcement with basalt mesh for reinforcing the wall masonry by means of bandages makes it possible to improve the compression strength by more than 30%. The technique of works aimed at reinforcing the masonry with bandages from composite mesh is more substantial and economic than standard strengthening methods on the basis of steel and reinforced concrete casings.
    Key words: composite mesh on the basis of basalt fiber, experimental studies, masonry reinforcement, large-size hollow-porous stone, casing in the form of bandage.

    Abstract. The article concerns the reconstruction of multi-functional health facilities, it is a high relevant challenge because of the rapid development of medical science and technology, as well as moral and physical obsolescence of a large part of multifunctional medical institutions in Russia. Possible causes for reconstruction, determining aims, volumes of the forthcoming reconstruction and ways of its realization have been studied. On the examples of domestic design experience, types of reconstruction depending on methods of changing the building volume are considered. They are construction of a new volume on the site of partial demolition, building vertical extension, annex of one or several volumes to buildings, changes of bearing elements of buildings without an increase in construction volume, stage by stage demolition of all facilities followed by a new construction with allocation of starting complexes. For each type of reconstruction, its advantages and disadvantages were identified, an analysis of feasibility of the use of a particular method depending on the cause of reconstruction and some other limiting factors (site capabilities, availability of funds, location on the territory of protected areas and architectural monuments) was made. Data obtained in the course of the analysis of reconstruction types for multifunctional medical objects can be practically used when forming the concept of modernization of healthcare facilities.
    Key words: reconstruction, medical facility, method of reconstruction, reasons for reconstruction, superstructure, demolition, reference object.

    Abstract. A number of disadvantages of the theory of eccentrically compressed concrete elements calculation, recommended by regulations, are considered. In contrast to the calculation by selection method, the proposed method is specific for the calculation of maximum load which the column can withstand. Calculations of eccentrically compressed concrete elements in the ultimate state of bearing capacity of normal sections include all possible cases of stresses appearance in the longitudinal reinforcement. Methods of calculation are based on the combined solution of the equilibrium equation of longitudinal forces and internal forces and the equilibrium equations of bending moments as well as additional equations which reflect the stress-strain limit state of eccentrically compressed concrete elements. The aim of the work is to improve, on the basis of the material contained therein, the calculation method of eccentrically compressed concrete elements proposed by current regulations. This will facilitate their more efficient and economic design, the improvement of reliability and durability of buildings and structures, in which eccentrically compressed concrete elements are used, in the course of their operation.
    Key words: bearing capacity, eccentrically compressed concrete elements, stress-strain state, equilibrium equation of longitudinal forces and internal forces.

    Abstract. The article describes a case of a dangerous pre-crash situation in the course of pit excavation under the protection of sheet piling wall with one shoring level under the conditions of historic development of the central part of St. Petersburg. There were registered deformations of sheet piling at the construction site and the neighboring buildings, exceeding the values predicted by geotechnical calculations. Excessive deformations were caused by the destructurization of weak thixotropic silt-loam soils, which are typical for the central part of St. Petersburg. Violations during the execution of "zero" cycle works (execution of pile field, sheet pile wall sinking, and arrangement of sheet pile unfastening band) contributed to it. Within the framework of scientific support, specialists of the St. Petersburg State University of Architecture and Civil Engineering proposed some measures which make it possible to execute safely remaining works of excavation of pit and construction of the underground space of new building blocks. The data of geotechnical monitoring of neighboring buildings settlement compared with the schedule of works are presented. Causes of the development of settlements and deformations of bearing structures of neighboring buildings were analyzed. The causes of deformation of sheet piles and neighboring buildings were analyzed. Conclusions and recommendations to minimize the settlement of adjacent buildings belonging to the zone of the construction influence were formulated.
    Key words: scientific support, thixotropic soils, geotechnical monitoring, neighboring buildings, fencing of pit, soft ground, computational modeling.

    Abstract. At present, current developments in the field of structures protection against humidity are aimed at new construction, but efficient methods for waterproofing restoration in the course of reconstruction and restoration of buildings are exist. Consequences of humidification of structures and changing properties of materials under the influence of moisture are analyzed. Problems associated with the restoration of cut-off waterproofing of existing buildings are presented. The article describes difficulties associated with horizontal basement waterproofing restoration of existing buildings. It presents a detailed analysis of the advantages and disadvantages of modern, traditional and experimental techniques of struggle against humidifying. Particular attention is given to three methods: mechanical method of waterproofing restoring, injection waterproofing and complex of measures based on the phenomenon of electro-osmosis. The mechanical method is installation of membrane isolation in the horizontal wall slot. The result is a durable waterproof layer, but the local slots around the perimeter of the building may reduce the load bearing capacity of the walls. The injection method consists in injecting the impregnating injection composition in the pre-drilled holes in the structure. The greatest interest is caused by technique based on electro-kinetic phenomena, since this technology could be the basis for an integrated approach to solving the problem of moisture (dehumidification, desalination and acceleration of walls impregnation process with hydrophobing compositions).
    Key words: waterproofing restoration, cut-off waterproofing, reconstruction, underground part of building, electro-osmosis, injection.

    Abstract. This article examines matters relating to the joint use of two software systems for determining the stress-strain state of elements of a spatial rod construction with due regard for yielding of foundation. The algorithm for the import-export of calculation models and the results obtained according to the scheme of SCAD 21.1-MIDAS GTS NX-SCAD 21.1. are proposed. As a result of the integration of programmatic complexes, coefficients of foundation deformability in space have been clarified. It is shown, that the most reliable results in addressing interdisciplinary problems can be obtained using the "strong possibilities" of two or more software products as in geotechnical modules with non-linear formulation, the assessment of the stress state with due regard for some external and independent from each other force factors is problematic, since it is impossible to use the principle of superposition.
    Key words: integration, software package, yielding of foundation, stress-strain state, spatial-rod structure, import-export of calculation models.

    Abstract. As a result of the analysis of the process of steel structures designing and the study of factors influencing on the quality of design solutions, it is concluded that the further development and implementation of computer-aided design makes it possible to reduce the labor-cost of designers and improve the quality and validity of design solutions. A functional scheme of the process of steel structures designing is considered; with due regard for this scheme, three basic systems, optimization of design solutions at the stage of variant designing, imitation simulation, and development of specialized program modules automating the solution of problems of synthesis, analysis and selection of design solutions for steel structures, are determined. The integration of these systems into a unified information technology is the methodology of automated search for support of design solutions for steel structures. The author presents a functional diagram of the design process, consisting of three blocks - regulatory, operational and constructive. A structure model of information technology, which can be used as a base for development of independent software tools utilizing the developed algorithms for solving local engineering problems, is presented.
    Key words: information technology, automation of design, imitation simulation, optimum design of steel structures.
