One of the priorities of socio-economic development of the municipality is the effective work aimed at improving the efficiency of territorial resources’ using, quality development, reconstruction and modernization of the network of educational facilities on the basis of proportional and balanced development of all urban areas, ensuring that the needs of the population in the objects of education and equal access within city. Scientific novelty of the research is the development of information and analytical support for decision support system for deployment of educational facilities on the basis of a geo-information database and simulation model of long-term scheduling of educational institutions in the reconstruction of urban areas. It allows for the collection, analysis, storage and subsequent presentation of spatial information based on GIS technologies, CAD and database systems.

Due to the increasing requirements of modern building materials increased interest in energy-efficient building materials. The dependence of the viscoplastic properties of slurries for foam concrete production on the composition and properties of the components of mix. To determine the regulatory properties of cement-sand slurries should consider the state of the water in a dispersed system.

The article shows that the viscoelastic behavior of polymers is well described by a nonlinear generalized Maxwell equation, generalized Russian scientists GI Gurevich In this paper, based on the results of experimental studies of the isothermal relaxation of thermal stresses presented a method to determine the relaxation parameters of the equation. The experiment was carried out on thin-walled tubes, with rigidly clamped ends. Heating or cooling from initial temperature to a final temperature (the temperature relaxation time) was carried out at a constant rate of heating (cooling) in a linear fashion. This work shows that the linearized theory does not give correct results.
Keywords: Thermal stresses, the Maxwell equations relating the parameters, isothermal relaxation
Denotes aneedin an engineering analytical correspondence between the loadand longitudinal strains of the composite columns. Experimental data on concrete longitudinal strains in the state of passive lateral compression are presented. The generalized form of correspondence for curvilinear "stress-strain" diagramof concrete the state of passive lateral compression is given.

Domestic construction materials industry produces expansive binders providing the concrete self-stress up to2MPa. A hypothesis on the catalytic role of lime in the formation of the active ettringiteis introduced. On the base of the hypothesis a proposal of the self-stress kinetics optimization with sulfate-containing mineral supplements, neutralizing lime in the early stages of the cement stone structure formation is given.

Given technological regime layering film coating on the paper.A significant change in the properties of the composite material at deviations in the mode of layers of film. The data testifies to the fact that a change in the regime of film layers, causing a deep penetration of the polymer in the paper and a violation can nolitnosti-coating reduces the strength of the resulting complex.

Mathematic model considers the geometrical and physical nonlinearity, the adaptability of creep flow. Arc work is accounted for by the method of constructive anisotropy, but with due regard for shear and torsion rigidity. In solving physically nonlinear problems, secant modulus is defined directly from the «σ-ε» curve, found experimentally. Mathematic model is written in the form of functional of total deformation energy. This model can be used for comprehensive analysis of the stability of reinforced shells of revolution.
Keywords: stability of reinforced shells of revolution, linear-elastic problems, the nonlinear-elastic problems, the problem of creep flow.
Petro graphic analysis of the structure of foam concrete, reinforced with glass dispersion and synthetic fibers showed that the real nature of the fiber controls the parameters of their structure and strength.
