the design of a new object presupposes not only the functional aspect, but an important factor is the location of the building or structure. The choice of location is one of the fundamental criteria: it is necessary to take into account the infrastructure and architectural appearance of the selected area, the needs of the district or region in the projected facility.

In this paper, the temperature distribution from a point source of heat under convective heat transfer is studied. The Navier-Stokes equation describing the steady two-dimensional laminar motion of a fluid is solved numerically. The distribution of the temperature field of a heat-loaded point source is obtained under appropriate boundary conditions, supplemented by the boundary conditions for the flow velocity to equal zero on the paraboloid walls by numerical integration using the control volume method.

In the paper, based on the linear equations of motion of an electrically conductive liquid lubricant for the case of a "thin layer", the continuity equation and Darcy, the exact self-similar solution of the problem of hydrodynamic calculation of a radial bearing with an electrically conductive lubricant is given. A field of velocities and pressures in the lubricating and porous layers was found in the work, in the following, analytical dependences were obtained for the main operating characteristics of a bearing with a two-layer porous coating on the shaft surface. An estimate is also given of the effect of the electrically conductive properties of the lubricant, the presence of a porous layer on the main operating characteristics of the bearing.

The results of a computational experiment performed in the Lira-SAPR environment are considered in the article. The purpose of the experiment is modal analysis of various structural schemes of multi-storey reinforced concrete frame under pulsating and seismic influences. The considered design schemes differ in the ratio of the frame and diaphragm components of the frame. It was calculated three series of samples, differing by the ratio of rigidity. The stiffness ratio varied from 20% to 65.9%. Within each series calculations were performed for seismicity of 7, 8 and 9 points. For each variant of seismicity, the soils of the 1st, 2nd and 3rd seismicity categories were considered. It is established that when the role of the frame part increases, the distribution of the modal masses shifts towards the lower forms of oscillations, and the numerical values of their frequencies decrease. Accelerations of the nodes of the coating from the ratio of rigidity do not depend. They increase with increasing seismicity of the site. The ratio of stiffness affects the total consumption of the reinforcement of slabs. This influence is significant in the range of values of the ratio from 20.5% to 42.5%. Further increase in the ratio of stiffness to the consumption of reinforcement influences slightly.

In the article an accent is done on the problem of fightagainst erosive processes in the regions of North Caucasus. It is marked that earth of recreational zones is windero dedand broken by economic activity of man. And the ant erosion actions and constructions used at the same time are inefficient, need improvement andecologization. Mountain earth is most subject to water erosion, inconnection with the abundant sinking and flow of the meltedwaters. By results of researches erosive processes on slope lands develop more intensively. The substantiation of the need for more effective erosion control measures. Based on the conducted studies the authors have developed more efficient technical solutions to combat water erosion and restoration of disturbed lands. The most effective designs of ant erosion constructions, author's development are offered. Which was found constructive and technological decisions on construction of erosion control structures of food-grade, biodegradable design to restore the ravines and pits of erosion.

The article substantiates the necessity of obtaining the dielectric properties of grain materials for studying the processes of microwave convective heat treatment of grain. The shortcomings of the existing methods for studying dielectric properties in the study of a fluidized bed and suspended layer are described. A laboratory installation and an experiment on the investigation of a suspended grain layer are described. The results of experimental studies on the determination of the dielectric loss factor of wheat subjected to microwave treatment are presented. The results obtained for different material densities correspond to the general dynamics, but differ significantly in level. Thus, for a dense layer, which corresponds to a density of 660 kg / m3 in the humidity range of 11-30%, the dielectric loss coefficient varies in the range 0.18-0.42; for the fluidized bed (440 kg / m3) 0.06-0.15; for the weighed (220 kg / m3) 0,1-0,3.

Within the Tresca yield criterion and its associated flow rule, the stress-strain problem in an elastic-plastic thin circular solid disk is considered under a temperature field such as the yield stress of the material depends on the temperature. In the central part of the disk the temperature is homogeneous. On the outer boundary, the disk is subjected to uniformly distributed pressure and constant temperature. The objective of the paper is to determine the service conditions which allow to obtain the temperature in the central part of the disk and its radius such as the initiation of the plastic zone starts either from the center of the disk or from its outer contour. The elastic-plastic boundary is calculated, and the plots for stresses and strains are presented. To verify the solution, the equivalent stresses for permissible plastic regimes are investigated together with the stress vector hodograph . The algorithm of similar problems is developed. The validity of the usage of the Tresca yield criterion when the yield stress of the material depends on the temperature is discussed.
