“…As well as, if necessary, a subsequent evaluation of the effectiveness of the application. [7][8][9][10][11] When designing low-rise buildings, it is crucial to form structures that have declared strength characteristics, reliability, thermal protection and environmental performance. No less important is the economic factor, focused on cost reduction in material and monetary terms.…”

The article discusses the possibility of using the criteria of energy saving, cost and comfort as an estimate criterion in the analysis of information modeling technologies for low-rise buildings at the stages of design, implementation and operation. The insulation systems of low-rise buildings, including frame type, are considered as an object of study. Different types of insulation systems of frame buildings are considered and, as a result, the expediency of using rolled polyethylene foam as an insulating material is established. Its use allows to form a seamless insulating sheath with minimization of heat transfer bridges, as well as to eliminate the use of additional wind-proof and vapor-insulating membranes. The regularities of the influence of operating factors on the thermal resistance of the insulating shell are established. The data obtained as a result of the implementation of experimental studies allow us to state that low water absorption and low vapor permeability of the insulating layer exclude the possibility of its wetting and degradation of heat-shielding parameters. The stability of the properties of the insulation sheath and the construction of the walls as a whole is ensured during the entire period of operation.

Subject of research: visualization of the wind regime of residential buildings on the slope area in the Arctic. Goals: the purpose of the study is to identify the problems of visualization of the wind regime on the slopes and the analysis of patterns of airflow around the sloping territories, affecting the comfort of pedestrians. Materials and methods: airflow patterns of slope areas with different characteristics and comfort assessment for humans are analyzed in the course of work. Geotechnical methods are presented in solving the problems of wind erosion and the stability of hillsides and complex terrain within the city limits. Results: The importance and novelty of the research in studying the relationship of slope geometry and environmental quality, as a decrease in comfort inevitably leads to a decrease in the development of nearby urban areas in settlements on the coast of the Arctic Ocean, problems with climate and local climate, as well as a decrease in the quality of life of people. The article considers the relationship of plastic relief with the aeration regime of the territory, the dependence of aerodynamic roughness on their height, features of aeration of the slope and hilly terrain, factors affecting the direction and speed of the wind and methods for studying the aeration regime of slope areas. Findings: The possibilities of applying existing approaches to research and visualization for slope areas are demonstrated. The direction of development of the technique for visualization of slope areas has been determined.

Introduction. The author solves a number of problems, including the substantiation of the required reliability level for steel-concrete beams in a reconstructed building, design parameters applicable to steel-concrete beams, use of probabilistic methods in the reliability assessment of steel-concrete beams, and reliability assessment of steel-concrete beams. Materials and methods. The engineering data, used in the reliability analysis, included steel beam examination and testing results, obtained by the Koucherenko Central Research and Development Institute of Steel Structures in 2017. The analysis was performed for the cases that took account of or failed to take account of the behaviour of a cast-in-plaсe reinforced concrete floor slab. A method of statistic simulation has proven that the probability values of snow loads set for Moscow by Construction regulations 20.13330.2016 are far below the true ones. This discrepancy reduces the reliability of the contour beams of the construction facility analyzed in this article. Results. B-12, B-45, B-49 and B-61 types of beams were used to compare the testing results with probabilistic calculations. Selected calculation results are provided in the article. An 8 mm deflection, caused by the temporary design load of 2.4 kN/m2 ensures the normal operation of a structure with a probability of 0.9973. Conclusions. A comparison between experimentally and analytically obtained deflection values has proven that the design model must have steel-concrete beams, rather than steel ones. Whenever a building structure is designed, its reliability level must be identified. The reliability of structures, having any criticality rating, depends on the values of the resistance probability in terms of their construction materials and the loads applied to them. Contour steel-concrete beams comply with the technology requirements and reliability values pre-set in the project documentation. Calculation results are validated by their convergence with the experimental data. Probabilistic methods should become a must in structural design. This measure can reduce the risk of failure or cut project costs.
