    Abstract. Concrete is the most versatile construction material. However, it is often turns to be environmentally unfriendly, as the concrete industry is responsible for about 5 % of global CO2 emissions, or for 2,1 gigatons of CO2 per year. In cement and concrete industry, the last achievements of concrete science, green chemistry, and new technologies should be applied. One of breakthrough strategies is based on the up-to-date concept which makes it possible to reduce the amount of cement in concrete due to use of mineral aggregates and various chemical admixtures. Another direction is based on the new principles of design of structures which makes it possible to achieve total reduction of anthropogenic impact on the environment, and takes into account life cycle of structures, performance requirements to durability, and the role of reinforcement, including reinforcing with non-metallic fiber, and external reinforcing with polymer composite reinforcement for repair and strengthening of structures. The paper demonstrates the peculiarities of nanostructuring of coarse-dispersed systems like concrete, due to application of finely-dispersed mineral particles. For obtaining such particles it is reasonable to apply cavitation technology of their grinding during suspension preparation. Nanostructuring provides consolidationof concrete structures and increases of concrete strength of 1,5-2 times.
    Key words: sustainable development, environmental impact, structural concrete, strength, structure, mineral fillers, composite materials, physical model, cavitation grinding, nanostructuring, technical regulations.

    Abstract. To use non-metallic rods as a reinforcing element, it is necessary to study in details the peculiarities of their operation in structures, as well as to create the normative base regulating the use of this type of reinforcement according to national building norms. In this connection experimental research in the use of non-metallic reinforcement in construction is required. Comparative tests of four sets of concrete samples, in centers of which the rods of composite polymeric fiberglass reinforcement of a periodical profile were fixed, have been carried out. A limit of bond strength of composite polymeric fiberglass reinforcement to concrete was determined with the use of axial extraction of the rod from the concrete cube under conditions of the long-term impact of water and air environments. Results of the study of changes in adhesion characteristics are presented. The effect of the impact of different environments on the characteristics of adhesion between fiberglass reinforcement and concrete has been assessed. The problem of reducing the adhesion of reinforced concrete samples under the long-term impact of water environment has been revealed. It should be taken into account when designing concrete structures which are reinforced with fiberglass reinforcement and operate under conditions of high humidity.
    Key words: composite polymeric fiberglass reinforcement, adhesion, experimental study.

    Abstract. The necessity of developing the computational substantiation of survivability parameters of structural systems and methods for their experimental verification with reference to frame-rod reinforced concrete frames of multistory buildings is shown. An algorithm of calculation and a physical model of a design of reinforced concrete frame for simulation of the survivability of non-linear deformed reinforced concrete frames of multistory buildings are proposed. The use of multilevel design schemes makes it possible to conduct the criterial assessment of the strength of reinforced concrete elements along normal and inclined sections and determine the sections of elements in which the limit state is reached. The authors have developed a technique for experimental determination of a structural survivability parameter and the coefficient of additional dynamic stresses for a experimental frame design at its structural rearrangement caused by the sudden failure of one of the vertical bearing elements. This technique can be used to develop recommendations on the protection of buildings and structures against the progressive ruptures for determination and regulation of parameters of their survivability.
    Key words: progressive collapse, survivability, reinforced concrete structures, beyond design impacts, multi-storey frame structures.

    Abstract. Proposals for improving the methodology of calculation of eccentrically compressed elements to the action of transverse force are made. The methodology contained in the normative documents offers the formulae for calculation of the required transverse reinforcement with due regard for the length of the inclined crack's projection. However, this parameter itself remains uncertain, only boundaries for its search are proposed. Calculation software often organizes the iteration process aimed at revealing the maximal value of the required reinforcement. But the final result depends on the accuracy of iterations and boundaries within which the search is conducted. Obviously, there is a reason for divergence of results of calculations by different software tools. The mathematical analysis of dependences of required transverse reinforcement in the column on the length of the inclined crack's projection has been made, as a result, the exact formulae have been obtained. A numerical example of calculation of transverse reinforcement in columns according to formulae obtained as well as according to recommendations of normative documents is presented. The influence of the longitudinal compressive force on the value of required transverse reinforcement has been studied. The algorithm of calculation of transverse reinforcement which can be used both for "manual" calculation and development of software products is outlined.
    Key words: inclined sections of reinforced concrete columns, transverse reinforcement in columns, length of inclined crack's projection, dangerous length of projection of inclined section.

    Abstract. Features of the stress-strain state of the monolithic beamless reinforced concrete slab with the orthogonal, free of pre-stressing, and diagonal pre-stressed reinforcements at the manufacturing stage are considered. A fragment of beamless slab of concrete B25, B30, B35, B40, where the reinforcement of "Monostrend" type, five ropes K1500 of 15,7mm diameter are used as pre-stressed reinforcement, was selected for the analysis. In order to clarify the distribution of clamping force along the volume of the plate, the solution of the Boussinesq problem was used for setting the width of the plate introduced into the calculation. The aim of the study was to determine the stresses in concrete, in pre-stressed and non-prestressed reinforcement for various classes of concrete and different levels of the transfer strength. Formulas for determining losses of pre-stressing are presented. The values of stresses in the pre-stressed and free of tension reinforcement in the concrete when transmitting the preliminary stress and after the occurrence of the first losses were established. Results of the analysis are summarized in the table where the stresses in concrete, in ordinary and pre-stressed reinforcement, at the different classes of concrete and levels of the transfer strength. Data obtained make it possible to expand the range of loads and also to increase the span sizes for beamless floors.
    Key words: mono-strand, pre-stress, monolithic beamless overlap, strength, bearing capacity, mixed reinforcement, loss of pre-stress.

    Abstract. During the construction of buildings and structures on soft soils sites, different types of pile foundations are used to eliminate the above-standard and irregular sediments. Under certain soil conditions and high loads on the base, the use of pile foundations is the only effective and correct decision. Traditional methods of designing pile foundations, especially of driven and jacked, lead to higher cost of foundations construction due to the incomplete use of piles material strength. The article gives a scientific substantiation of the possible use of a new design - piles of increased bearing capacity. The results of complex experimental and theoretical studies, on the basis of which the design scheme and the formula for determining the pile bearing capacity regulated by normative documents in relation to the pile of a new design have been improved, are presented. A comparative analysis which shows the advantages of the new pile design in comparison with the prismatic pile traditionally used is also presented. Data obtained can be interested both for researchers and for development of foundation construction technology under difficult soil conditions.
    Key words: piles of increased bearing capacity, prismatic pile, driven piles, pile foundations, ground resistance.

    Abstract. The authors develop the theme of infill development which is a necessary tool for solving problems related to improving the quality of life of citizens on developed territories. Regulatory documents concerning town planning issues at reconstruction and development of residential quarters, micro-districts, and functional zones are considered. Facts indicating that at the level of yard space intended for location of an object of infill development, the regulatory base, in some cases, can't give a solution that would satisfy the parties concerned (developer, authorities, inhabitants) are presented. Examples are given as contrary to the Declaration on the sustainable development of society in relation to the conservation of the natural environment, attempts to modify natural components and their combinations are made. The main directions of research in providing the ecological safety of urban environment are analyzed. The main criteria that characterize the environmental safety of the yard space on developed territories when locating the object of infill development are proposed. It is noted that, when studying the microclimate of the yard, certain factors of the formation of microclimate of the city under extreme weather conditions should be abolished, but some factors, on the contrary, should be more developed and detailed. It is concluded that the environmental safety of developed territories, when locating objects of infill development on them, should be provided by agreeing the design capacity of the facility with environmental factors.

    Abstract. Network methods of planning and management are forecast indicators for the implementation of the complex of construction processes. They make it possible to solve problems of not only forecasting and long-term planning, but also operational management. Due to the influence of external destabilizing factors and the ability to choose different ways of achieving the goal set, it is necessary to introduce new logical relationships into network models. The flexibility of network planning makes it possible to generate an optimal bid. Construction companies increasingly use software systems, aided by network models of planning and management. If the initial calculated date of project completion is unacceptable, then the values of the corresponding resources, and sometimes the content of the project must be changed. In this case, the resource planning starts with the works of the critical path. The article contains several methods for optimizing network schedules in time which make it possible to get an objective assessment of parameters for the selected variant of works structure and resource distribution.

    Abstract. A scheme of heating system in which one of the control valves is excluded and for realization of its functions the mixing pump is used is offered. Such technical solution gives the chance to reduce the cost of heat supply system, to increase its reliability and to optimize production costs of providing the served buildings with heat. The modified scheme of multiple-loop system of heat supply in which dependence between efficiency of the control valve and the mixing device in each heating contour is considered has been developed. Minimization of a metabolic cost in this scheme is carried out due to the rational distribution of thermal energy between heating contours. The algorithm of management of the multiple-loop system of heat supply with dependent connection to thermal networks providing the minimization of energy consumption in system at the given temperature schedules in the heated premises is offered. According to this algorithm, the thermal energy is redistributed between heat supply contours with due regard for their interaction.
