Scientific and technological progress in the field of construction is closely related to the problems of development and improvement of steel products and structures. The introduction of lightweight metal structures is important for the development of industrial construction technologies for the workshops of metallurgical enterprises. Reduction of the weight of structures leads to lower transportation costs and simplified installation. To further improve the process of design, manufacture and installation of lightweight metal structures, a combination of optimal material characteristics is necessary. In the production of metal structures, low-carbon steels are usually used. This study suggests the possibility and feasibility of increasing efficiency through the use of steels of other grades (St2sp, St3sp, 30, 45, 40Kh, 65G). Steels of various grades were considered, their stress-strain state (SSS) under the influence of static loads was studied, and their influence on the strength and deformability of metal structures was assessed. The study substantiates the theoretical possibility of using other grades of steel to create a building structure, which makes it possible to expand the range of steel structures in general. Numerical studies were carried out in the calculation software package Lira 10.12, taking into account the linear physical model of the materials under study, which makes it possible to estimate the actual stress-strain state ofstr uctures considering variations in steel grades. The use of other grades of steel enables to increase the strength of a steel structure by 1.52–22.44 % and reduce deformability by 3.5–35.47 %. According to the results of the study, St65G steel was recommended as a material for metal structures, the use of which in the manufacture of tensile truss elements makes it possible to reduce their overall material consumption by reducing the size of the cross sections. In this regard, there is a scientifically based possibility of reducing the cost of structures while maintaining their load-bearing capacity.
The work was carried out within the framework of the state assignment in the field of scientific activity of the Ministry of Science and Higher Education of the Russian Federation (topic FZUN-2020-0015, state assignment of VlSU). The research was carried out using the equipment of the interregional multidisciplinary and interdisciplinary center for the collective use of promising and competitive technologies in the areas of development and application in industry/mechanical engineering of domestic achievements in the field of nanotechnology (agreement No. 075-15-2021-692 of August 5, 2021).
