The paper studies the problems of the modern architecture and planning of houses of culture intended for people of different age. The paper considers modern culture and leisure centers, analyzes the main approaches to the renovation of the architecture and planning structure of houses of culture, culture and leisure centers and cinemas, and highlights the design problems in the conditions of preserving the architectural and spatial environment.

The paper considers the main formative factors of the architecture and planning structure of houses of culture and analyzes the social functions of modern culture and leisure centers. The organization of leisure centers is connected with preservation of cultural and educational centers of the Soviet period, that do not meet the modern criteria (normative, architectural, artistic, planning and social). It is therefore necessary to create modern centers, in which the architecture and planning will satisfy a wide range of interests and creative opportunities of people.

The purpose of the paper is to study the architecture and planning factors of houses of culture in Novosibirsk for the creation of new multifunctional culture and leisure centers, taking into account the socio-cultural needs of people as well as modern trends in architecture.

The research methodology includes a comparison and systematization of the literature, Internet resources on the history of architecture of Novosibirsk, analysis of historical, economic, aesthetic and socio-cultural data relating to the formation of the architecture of cultural centers as well as culture and leisure time of people in the city of Novosibirsk.

Research implication include the factors influencing the formation of the architecture and planning structure of houses of culture such as functional-planning, landscape-visual, artisticaesthetic, socio-cultural, etc.

A study of the history of formation of houses of culture in Novosibirsk and the modern design experience show that these objects are multifunctional spaces created for active and enthusiastic people involved in various creative activities. Houses of culture are a place of inspiration, creative self-realization, intellectual and physical development, leisure, recreation and communication, a place where the ideas of a progressive society of the 21st century can be realized.

Orthotropic concrete reinforcement is the addition of spiral fibers to concrete. Finite element modeling is used to study the influence of the spiral fiber geometry on the physical and mechanical properties of concrete. Based on the numerical and experimental research, the proposed mathematical model of fiber-reinforced concrete shows that the composite with the desired properties and structure is obtained with the optimum parameters of the spiral fiber namely 20-30 mm length, 5 mm diameter, and 1.5 mm distance between turns.

The paper studies the flow rate of asphalt cement described by Herschel–Bulkley fluid in a cylindrical pipe. The dependence is suggested for the fluid flow rate and the pressure drop. It is found that with increasing content of paraffins and resins, the yield stress and consistency of the medium increase, thereby leading to a decrease in the flow rate parameters at a given pressure drop.

The paper presents the experimental results of the plasma-assisted production of glass-ceramic materials. The dependences are suggested for the main physical and mechanical properties (flexural and compressive strengths, density, thermal expansion coefficient) of the end products and the mixture components. The accumulative recrystallization centers of the anorthite phase are detected. The inclusions of this phase randomly locate on the surface of the melting products and resemble dendritic microinclusions up to 90 nm in size. The properties of the glass-ceramic materials are described using conventional techniques.

The paper presents the research results of peat-vermiculite compositions for the production of granulated material with heat-insulating properties, that can be used in the construction of low-rise buildings. The paper considers the possibility of producing a heat-insulating granulated material based on a peat-vermiculite mixture. The obtained data on various methods of the peat-vermiculite mixture granulation are analyzed. It is found that the optimum concentration of the Akvasil water-repelling is 10% in the mixing water. This concentration allows reducing the water absorption of peat-vermiculite compositions by 16% and increasing the material strength by 20%. Further increase in the Akvasil concentration in the mixing water does not lead to a significant change in the water absorption, and the strength properties decrease.

The paper presents research results of natural hardening of lightweight concrete with aluminosilicate ash generated by the Thermal Power Plant in Seversk (Tomsk, Russia). Today, it is necessary to develop effective building materials with improved operational properties by using local natural and technogenic raw materials. The acceleration of the structure formation and required plasticity for a transportation and molding of lightweight concrete products are achieved by using finely dispersed aluminosilicate minerals and plasticizers for natural hardening of lightweight concrete. The concrete mixture and lightweight concrete are studied in the TSUAB laboratory accredited in accordance with national standard requirements. The optimum content of hydraulic ash in lightweight concrete mixture is 10–15 wt.%. the compressive strength lightweight concrete with D400 density increases by 26−66 % after 28-day curing, when adding the Relamix T-2 plasticizer and ash from the Thermal Power Plant. Its water absorption reduces by 30 wt.% with insignificant decrease in thermal conductivity. Technological solutions are developed for the production of lightweight concrete with ash ash and slag materials for wall structures in individual housing construction.

The paper studies the possibility of using calcium-ferritic slag in the cement production. The chemical analysis shws the instability of the calcium-ferritic slag composition. Experimental and test raw mixtures are fired at similar temperatures without deterioration of the clinker formation process of raw mixtures containing calcium-ferritic slag. The quality evaluation of clinkers is performed for cements obtained by grinding with the addition of 4 % calcium sulfate up to a specific surface of 300 cm²/g. This paper shows the possibility of using the calcium-ferritic slag obtained during the complex processing of pyrite as a correcting component of the raw mixture at its consumption 1.3–1.5 times higher than pyrite cinders.

For the first time, this paper studies the fundamental conditions of the dynamics of bridge spans under non-stationary oscillations with regard to the mass inertia of the span–vehicle system. Based on the dynamic analysis of the stress-strain state of spans under changing live load, the mechanical and energy principles of additional dynamic load characterized by the dynamic coefficient, are formulated and substantiated. It is found that the dynamic coefficient slightly depends on the system vibrations due to the temporary nature of its application. The amplitudefrequency characteristics of the dynamic stress-strain state are considered in the mode of stable oscillations only. Theoretical and experimental studies of road bridges of various designs and lengths confirm the relationship between the dynamic coefficient and the parameters of damping and resonance. It is found that the dynamic coefficient reflecting the energy balance of the system allows considering the critical ratios of the equilibrium amplitudes and dynamic stiffness of the spans under the changing effect of the live load as well as the presence of road defects and span bearing elements in terms of the well-known Hurwitz criterion.

The relevance of the work is determined by the need to improve the properties of the road pavement layers. Under conditions of increasing carrying capacity of vehicles and traffic intensity, pavements designed and constructed in accordance with the regulatory documents are destroyed without reaching the required service life. The pavement reinforcement with chemical fibers is one of the ways to solve this problem. The aim of this work is to study the structure formation of dispersion reinforcement of the pavement layers made of organomineral mixtures. Theoretical calculations are presented for the structural formation with directional reinforcement by using meshes and interlayers with dispersed reinforcement. It is shown that directional reinforcement of the structural layers provides compensation of tensile stresses only at the bottom layer, where the mesh locates. At the edges of the deflection bowl in the upper layer, tensile stresses are not compensated because the reinforcing mesh locates at the bottom layer. With dispersed reinforcement, chemical fiber penetrates in the structural layer, including its top and perceive tensile loads and reduce the likelihood of cracking. The implementation of the liquidphase method of dispersed reinforcement of organomineral mixtures improves the bitumen adhesion to the fiber surface of the dispersed reinforcement.
