    Abstract. The aim of this work is to analyze the impact of the variability of deformation characteristics of concrete on the bearing capacity of flexible reinforced concrete elements. The urgency of this issue is due to the widespread use of a nonlinear deformation model for the calculation of reinforced concrete structures. The peculiarity of calculations with the use of the non-linear deformation model is in the need for joint use of strength and deformation characteristics of concrete. At that, the current rules contain the average values of these characteristics and there is no information on their variability in the rules. As a result of numerical experiments the significant impact of the variability of deformation characteristics of concrete on the bearing capacity of a flexible reinforced concrete element at large percentage of reinforcement has been revealed. The influence of deformation characteristics on the values of marginal rate of reinforcement and limit height of the compressed zone has also been defined. Thus, the application of average values of deformation characteristics of concrete in calculations with the use of the nonlinear deformation model leads to a significant reduction in the reliability of heavily reinforced concrete structures.
    Key words: probabilistic method, ratio of reinforcement, deformation characteristics, flexible reinforced concrete element.

    Abstract. Some structural conceptions of precast and monolithic reinforced concrete floors which are used in the construction of multi-storey building are considered. Floors transmit the load on vertical bearing structures, form horizontal disks which combine columns with vertical connections, as well as influence on horizontal movements and vibrations of the frame. A pre-fabricated design of the floor makes it possible to assemble ready-made elements at the construction site. Floors made at the construction site as monolithic slabs give the designer the opportunity to select variants: to use a profile flooring as a permanent formwork or as a reusable formwork fixed at the design level before the concrete pouring. The development of optimal design of floors meets modern trends of designing and makes it possible to select the best design solution for specific conditions of construction and operation of the building.
    Key words: steel frame, multi-storey building, floor made of pre-fabricated reinforced concrete slabs, monolithic reinforced concrete floor.

    Abstract. The analysis and systematization of methods for calculation of three-later wall and roof sandwich panels with metal sheeting are made. The basic loadings and impacts influencing on the stress-strain state of sheeting and filler, and also their calculated combinations are considered. Own weight, snow weight and erection load (for roof panels), and also the active component of wind pressure (for wall panels) are accepted as the main loads. Calculations of roof panels take into account the influence of temperature and filler creep, and calculations of wall sandwich panels - the temperature influence only. Criteria for evaluating the bearing capacity of sandwich panels are specified. Tables indicating the main criteria of bearing capacity estimation for wall and roof panels with different quantity of spans are presented. Tables are generated as a result of the automated calculations by the method specified in this article. The systematic method for estimating the bearing capacity is recommended to be used by specialists of the enterprises engaged in the manufacture of sandwich panels.

    Abstract. The formulation of the problem of heat and mass transfer in a multilayer wooden glued laminated lumber is presented. The system of differential equations in private derivatives is considered. The equations describe the non-stationary process of heat, mass and baro-transfer under really possible conditions of operation of enclosing structures. It is revealed that the thermo-technical calculation is the defining parameter when designing enclosing structures made of wooden glued beam. Wood is a natural material which incorporates both a knot-free part, and parts with knots with the high heat conductivity. A mathematical model of the process of heat transfer is offered. The equation of heat conductivity of Fourier, entry and boundary conditions at the joint of lamellas of a wooden glued beam, and also at the joint of knotty and knot-free wood within one lamella is a cornerstone of this model. The model makes it possible to define the heat conductivity coefficient for separate parts of a beam. The solution of the problem of heat conductivity on the basis of the method of finite elements and mathematical model reflecting the interrelation of a macrostructure of wood and its heat conductivity will be considered in the subsequent publications.
    Key words: multilayered glued wooden beam, lamella, heat and mass transfer.

    Abstract. Concepts of design and operational moisture of building materials are defined; the relevance of the problem of determining the calculated moisture is justified including by results of field investigations. An analysis of alternative methods for determining the operational moisture is made. The dependence of heat conductivity of building materials on the moisture content is considered; the methodology for appointment of the calculated moisture of building materials using the sorption isotherm is also described. References to normative documents, concerning the use of methods necessary for numerical calculations of moisture characteristics of building materials, are given. A new formula for calculating the operational moisture according to the results of field investigations of moisture of enclosing structures, which improves the accuracy of the research, has been obtained. The results of field and laboratory studies with the aim to determine the design moisture content of building materials are presented. The discrepancy of the results of field investigations with laboratory data is shown, thus the inadequacy of method for destination of the design moisture of building materials according to the sorption isotherm is proved. It is proposed, as the most promising method, to determine the moisture content by numerical calculations with verification of the data with the results of field studies.
    Key words: design moisture, operational moisture, building materials, thermal conductivity, field investigations, moisture behavior, unsteady calculation method, the sorption isotherm.

    Abstract. Problems of the use of copper smelting manufacturing waste, as a fine ground mineral additive, for producing the concrete with technogenic waste are considered. This area of research is relevant because of growing rates and scales of construction. In particular, in the course of concrete works execution, the use of new complex additives on the basis of industrial waste is an important factor influencing on their efficiency. Copper slag dumps located in the Ural Federal District haven't been widely used in construction or in other industrial branches. Rational utilization of copper smelting manufacturing waste makes it possible to solve ecological problems of many regions of Russia. Results of the study of the period of concrete mix structure formation with the use of ultrasonic and thermal methods are presented. The diagram of thermal variations of concrete mix with fine ground admixture within 24 hours of hardening under normal condition which reflect the passage of chemical reactions and the formation of new products of the hydration of mixed binding systems is shown in this article. The data obtained make it possible to predict the positive and significant impact of this additive on strength and operational characteristics of concrete and, as a result, organize the rational utilization of copper smelting slag for concrete manufacturing.
    Key words: cooper smelting slag, utilization of technogenic waste, fine ground mineral admixture, concrete with technogenic waste, mixed binders, forming period of concrete structure, ultrasonic study.

    Abstract. This article is devoted to the analysis of the problem of improving physical properties of ceramic wall materials. The existing options of used efficient enclosing structures, their advantages and disadvantages are considered. The negative effects of the usage of the most effective wall ceramic products in the form of porous-hollow stones of a large format are noted. The article also describes the method for obtaining highly porous ceramic products due to the use of rice straw as a combustible addition, which, when burning in a reducing environment, can form any significant amount of amorphous silica which is able to interact with the products of roasting and improve the structure, properties, and performance characteristics of ceramic crock. The study of the influence of rice straw addition in the clay composition on the change in its thermal conductivity were carried out in the ISA MGSU Laboratory of Building Physics by measuring the rate of change of temperature during heating the cylindrical probe immersed in the sample of material of a certain form, in accordance with GOST 30256-94. The results obtained show that the introduction of combustible addition of up to 10% of fluffed straw into the clay reduces the density of annealed samples and coefficient of thermal conductivity, i.e. their thermal conductivity values are converted from class ineffective to effective class of wall ceramic materials.
    Key words: wall ceramic materials, rice straw, amorphous silica, thermal conductivity, thermal resistance, large porous hollow products.

    Abstract. The article describes the theoretical data on the use of fine-grained road concretes, highlights the main problems of their application and features of designing their compositions. Particular importance is given to the study of the sand and cement ratio in the mixture as an important parameter of optimizing structures and change in the volume of cement paste with an increase in the proportion of sand. Results of the study of fine-grained concretes and fiber-reinforced concretes, including dependences for calculation and prediction of structural, technological and strength characteristics at different ratios of sand and cement are presented. Peculiarities of the application of polypropylene fiber as an effective multifunctional additive, which contributes to the improvement of strength properties of concrete, are analyzed. It is confirmed that the increase in fiber consumption leads to the reduction in the concrete compressive strength and increase in its flexural strength. An integrated approach to the study of fine-grained concretes made it possible to estimate the consumption of mixture components and parameters of their variations, obtain mathematical models and prove the influence of the content of sand, cement and fiber on the main indicators of quality of concretes. Dependencies obtained can be used to analyze and predict the properties of concretes and fibrous concretes on the basis of different types of cement and multi-component and mixed binders.
    Key words: fine fibrous concrete, structure, polypropylene fiber, strength, density.

    Abstract. Peculiarities of the development of factory complexes of Kostroma Governorate, the middle of XIX - early XX centuries, are presented. Their two main zones are revealed. They are industrial one and public-residential. The public-residential zone can include five groups of public buildings. The first group - residential buildings; the second group includes the building of educational purpose (nurseries, kindergartens, schools, colleges); the third group is the buildings of health (hospitals, infectious barracks, dispensaries, maternity homes, pharmacies); the fourth group - culture and leisure, and religious buildings (people's houses, libraries, teahouses, temples), and the fifth group - buildings servicing the population (stores, stalls, shops, canteens, bathhouses). Considering the architectural-spatial structure of the factory complexes in Kostroma Governorate of the indicated period, we can distinguish three main types of factory complexes. The first type is complexes having only an industrial zone. The complexes of the second type includes buildings of industrial and public-residential zones which don't have the complete composition (not all five groups of buildings listed above are presented). The third group includes industrial complexes with industrial and public-residential zones, moreover, the public-residential zone is presented in full, and consists of all five groups.
    Key words: factory complexes of Kostroma Governorate, industrial buildings, public buildings, industrial and public-residential zone.

    Abstract. Pile and crib structures of the Kostroma lowland, as works of folk architecture, are notable for constructive reasonableness and individuality of each structure. Created on the areas which are flooded at the time of spring flood, these structures are an example of developing these sites adverse from the point of view of natural features. Piling buildings of the Kostroma lowland, the lost Church of the Transfiguration 91713) in particular, became the object for exploring by outstanding researchers of the Russian wooden architecture. Monuments of the Kostroma lowland became the core of the architectural collection of the Kostroma Museum of Wooden Architecture. Results of the analysis of structural and architectural features of the construction of "hanging" villages of the Kostroma lowlands are presented in this article. The options of pile and crib structures for footings of timber constructions are considered. Examples of the most characteristic monuments of wooden architecture of the lowland, explored and transported in the Kostroma Museum of Wooden Architecture, are given.
    Key words: wooden architecture, "hanging" villages, pile foundation.

    Abstract. The issue of increase of reserves of the urban development process efficiency, in particular of public housing objects, has not been systematically analyzed In Russian and foreign practice. Among the factors determining the efficiency of the organization, labor performance is one of the basic indicators of characteristics variety to determine the economy status, particularly in the construction industry. The cost-based approach was used to value labor performance, which is regarded as triple economic characteristics. The normative settled object value is counted as a targeted investment program in accordance with the structure confirmed in construction cost estimate summary. The actual value corresponds to the payments of state organization customer net the damage amount identified during the retreat of the actual organization of the urban planning regulations process. This research shows the author's method of labor performance growth reserves analysis. It is based on a comparison of the normative and the practical models of urban development process, evaluation of potential damages caused by the terms of performance stages in these models derivation. Labor performance growth reserves are determined by comparing the actual and regulatory performance.
    Key words: performance efficiency growth reserves, urban development process, normative and practical models of urban development process, labor performance, estimated damages.

    Abstract. The practical application of the design techniques of basic parameters of impervious structures of a "wall" that is implemented in the calculated complex of a computer is analyzed. To use the results obtained in engineering calculations, tables and charts, which make it possible, varying structural parameters for initial data, to define the technical efficiency of impervious structures, have been compiled. Examples of the calculation, determination of the "wall" width, characteristics of the filler material, loss of pressure in the soil body, in the section before the "wall", permissible water inflow, technical efficiency under the given constraints, are presented. Prediction of these parameters, distribution of pressures beyond the contour of the pit and water inflow will make it possible to avoid negative consequences, deformations of buildings and structures adjacent to the construction site.
    Key words: impervious structures, calculation of basic parameters, technical efficiency.

    Abstract. A number of factors that significantly affect the conditions of deformation of concrete samples during the test are considered. To improve the objectivity of test results, it is first necessary to minimize the value of the abrasive component of an integral force. With this purpose, the methodology, according to which a visco-plastic element was installed between the contact surface of the sample and the plate of the testing machine, has been developed. To analyze the stress-strain state of an isotropic concrete sample under loading, a model of the elasto-plastic body, which is recommended for calculating concrete and reinforced concrete structures according to limit states of the first group, was used. Boundary conditions were defined in terms of displacements, the value of which does not exceed the limit elastic values calculated by the value of elastic limit deformation. Results of the numerical solution with the use of the software ANSYS are presented. The overall picture of the stress-strain state makes it possible to conclude that contact pressures are extremely uneven distributed on the contact surface at the maximum value of the friction coefficient.
    Key words: Poisson's ratio, isotropic concrete sample, compression, displacement, strain, visco-elastic layer, model of elasto-plastic body.
