The article discusses the concept, content of activities, phases of the corporate social responsibility management process, functions and CSR management system. Based on the analysis of various approaches to determining the content of social responsibility management, typological characteristics of the CSR management process are highlighted. The thesis is substantiated that the CSR management process includes additional functions, along with the traditional management functions adopted in management. The paper also describes the corporate organizational mechanism of CSR management on the example of large public joint stock companies.

The article analyzes and summarizes the principles of architectural bionics applied to various construction and technical structures. The analysis was carried out in the course of studying the scientific literature on the topic “Bionics. Architectural structures». The purpose of this work is to study the principles of architectural bionics, to study the possibility and effectiveness of their application for solving engineering and technical problems. The main task of the work was to study the directions and principles of development of architectural bionics, to assess the effectiveness of their application for solving technical problems, to find the correspondence of biological systems to construction and technical structures and facilities, to analyze known architectural structures from the point of view of architectural bionics.

The methods of designing fullerenes and nanotubes are presented. It is proved that in the construction of nanotubes, regardless of the method of production, there are 12 pentagons and a practically infinite number of hexagons, thus satisfying the Euler theorem for polyhedra.

When designing modern sports complexes for architects and designers, it is necessary to work out both the ideological and functional aspects of the project. To create comfortable conditions, to ensure the requirements of acoustics, noise insulation and thermal insulation of it from other rooms and the environment, the design of the sports complex's coverage becomes crucial. Bearing coating structures are the most important constructive element of sports facilities. To date, there have been developed sufficiently typical projects with frequently used spans from 18 to 36 m. Coatings with a span of more than 36 m are already considered atypical and are designed individually, based on conditions. Analyzing the existing sports facilities, it was found that a wide distribution as a covering of buildings of sports facilities with a span of up to 60 m was obtained by plane structures: arches, trusses, frames. In this paper, a comparative analysis of the plane structures of the cover for a span of 60 m in the LIRA-SAPR program complex: a truss with steel columns and a steel frame is carried out. All load sensing and effects on structures are specified in accordance with SP 20.13330.2016. The results obtained in the analysis of foreign and domestic experience in the design and construction of these structures can be used at various stages of designing large-span sports complexes.

Today, indoor stadiums are an indispensable attribute of modern sports. Our country occupies territory with different climatic conditions. These conditions leave their imprint on the space-planning and design solutions of buildings. Modern indoor sports facilities are distinguished by their original appearance, large capacity, unusual shapes and coating designs. The use of large-span structures makes it possible to make maximum use of the load-carrying qualities of the material and thereby obtain light and economical coatings. The most promising and economical are thin-walled spatial architectural and construction structures for covering buildings and structures. The results obtained in the analysis of foreign and domestic experience in the design and construction of these structures can be used at various stages of designing large-span sports complexes.

The author of this article refers to the personalities of the Czech scientist Klokner, whose name is assigned to the Institute located in Prague. For 95 years, this Institut conducts scientific and educational activities. It is part of the Czech higher technical education institution, formed more than three centuries ago.

It is shown that the choice of types of construction and modernization of logging trucks for hauling wood are the most important factors to increase the economic accessibility of forest resources.

The authors of this article note that the fast pace and modern construction make qualitatively new demands on building materials and structures. While great attention is paid to the production of glued wooden structures. Such designs on a number of technical and economic indicators are superior to metal and concrete have low component weight, relatively high strength and stiffness with sufficient reliability and durability. At the same time, negative characteristics of the wood (the dependence of the properties from its structure, defects, need for and considerable expense of quality timber, excessive massiveness of the cross-sections, creep under sustained loading, etc.) restrict the scope and impair the indicators of glued wooden structures. One of the ways to address these shortcomings and increase techno-economic efficiency – reinforcement of sections of glued wooden structures and elements of steel or fiberglass reinforcement. This can significantly reduce the consumption of wood, reduce Assembly mass, to improve the quality and reliability of wooden structures, working mainly in bending and compression with bending.

It shows that to ensure the effective functioning of large timber structures requires extensive transportation network, which will provide transportation with minimal cost of significant volumes of timber cargo, as well as meet the transport needs of other sectors.
