The analysis of improving ways to test for load-bearing structures - metal beams with corrugated wall was conducted. «Weak» places, limiting their load-bearing capacity were determined. It was found that the criterion for determining the carrying capacity of thin-walled corrugated beam is its local resistance. The author's solution to increase the local stability of the corrugated wall beams was suggested. Author's solution is to give the corrugated wall of further extruded profile of different geometry. The influence of the shape and size of punching the wall on the carrying capacity of corrugated beams was determined. The studies confirming the effectiveness of the proposed constructive solutions increase the stability of the corrugated wall are conducted. Preliminary assessment of the degree of increase of the bearing capacity of the beam by punching its wall is obtained.

This article defines the options to improve the efficiency of local exhaust ventilation systems by incorporating into the circuit from the air cleaning devices droplet aerosol. Schemes connecting cleaning apparatus in ventilation management system are worked out. In the first embodiment, the placement aerozoleulovitelya purified ventilation air is discharged directly to the atmosphere, in the second embodiment, the cleaned air is used in the recovery system, which is removed after the street. The feasibility of using the heat exchanger in the scheme is justified by comparing the technical and economic options and the need to improve energy efficiency. The method of selection and calculation of air cleaning devices from droplet sprays, on the basis of which it is possible to determine the design parameters of the system, to evaluate the amount of captured material, and choose the most appropriate in each case unit, focusing on the desired performance of the ventilation system, the necessary degree of purification and the area for mounting the device.

The results of the analysis of the state diagrams of binary systems on the formation of solid solutions based on Al2O3 and Cao. Multi-criteria methods it is demonstrated that trivalent cations among the greatest affi nity with alumina structures-tion and technological parameters (valence, the size of the cation, the latt ice parameters, t-PU patt erns) observed in Fe2O3. It is established that on the basis of Cao the formation of solid solutions with the iron oxide. This approach allowed the development of basic technological parameters of obtaining nizkogorjyami ceramics and compounds.

Various sources of noise, the noise shaping mode of an apartment house are studied: external noise (the source of which is mainly highways); within a yard of noise sources (parking lot of tenants, container platforms, transformer substations, sports and children’s playgrounds, etc.) and in-house sources of diverse nature of noise (this sanitary equipment, boiler roof, equipment shops, cafes, offices, and the livelihoods of the residents themselves). Listed noise protection measures when selecting the construction site, local area planning decision. The methods and problems of protection from noise sources outside the house and inside it are analysied. An algorithm for the creation of acoustic comfort in dwellings at the stage of designing the house is suggested.

Based on the research of humanitarian specifics of architectural form and architectural objects, three aspects are defined, from the position of which the CM system is adjusted the concept of the architectural object as megaobject (interconnected system of object and the physical environment) and how metaobject (conditioning facility, cultural space). The first aspect - the role of the binary opposition, meaning that in the architectural form of the object and system identification, or in a non-obvious, presented meanings that oppose each other, but do not displace each other. The second aspect - the presence of “external environment” (URBO landscape and cultural space). The presence of the environment, the environment has a formal aesthetic and ethical justification. As a result, the environment may become a challenge no less important than the object. The third aspect - the fundamental metavalue of architectural object, the method adopted in the composite as a basis. It relates to the interaction between the city and the house - two metavaluesi, covering almost all the layers and subsystems which appear in the process of interaction between the author and architectural form. This fundamental aspect is defined in the article as a universal binary formula “House-City.” The binary formula “House- City” determines the methodological structure and content of the genesis of the CM process carried out in phases as a gradual transition from the experience of abstract form to the project.

The article deals with summarizing and analyzing the background and modern international experience in improving of the architectural and spatial environment of universities. It was found that the activity of higher education institutions are currently based on strategic planning, which includes the development of a roadmap for sustainable management. It was noted that the most prestigious universities are paying special att ention to the creation and development of infrastructure for the study of the environmental, social systems and educational activities. During the reconstruction and construction of various buildings usage, environmental technology is implemented. A common phenomenon is the certifi cation of university facilities for “green” standards.

The article examines the anonymous architecture in terms of aesthetic knowledge. A parallel between the categories of classical aesthetics - a beautiful / ugly, and the categories of architectural activity in the Vitruvian paradigm professional / anonymous is drawn. Traced the background and process of incorporating objects anonymous architecture in non-classical aesthetic field through “poetization everyday life”, the emergence of technical aesthetics, aesthetics and functionalism of modernism. Non-classical aesthetics characterize objects anonymous architecture using parakategory “daily”, “physicality”, “thing”. We present the aesthetic characteristics of the anonymous architecture using the categories developed in the traditional aesthetics of eastern cultures - wabi, sabi, sibui and eugen. A parallel between the perception of the aesthetics and simplicity of anonymity is drawn.

In the article the central urban areas are treated as centers of gravity of social activity of the urban population. The article deals with the problem of the lack of a unified artistic image of the central area planning Togliatti city. It is given a brief analysis of the currently existing works on the subject, stated the purpose, objectives and hypothesis of the research of the topic. The central area of the city are treated as special functional zones, places where social activities and public facilities, combined into a single plan's architecturally-spatial and compositional system, where the urban population can satisfy the diverse cultural and household needs. Besides, it is accentuated the areas, which are the most significant for the presentation of the city as a whole, which intended to clearly reflect and concentrate the city's main features Togliatti.
