Аннотация: Reinforced concrete structures are a system consisting of monolithic reinforced concrete, a steel part and connecting elements. In this article, the stress-strain state of the structures of a high-rise building is considered. The domestic experience of research and application of steel-reinforced concrete load-bearing structures is described. The analysis of the strength and stability of the most loaded column of a high-rise building is presented. The columns of the object under study are made using tubular concrete, which is a steel shell pipe working in conjunction with concrete and design fittings. Detailed finite element modeling of each tubular concrete column is labor-intensive and not optimal from the point of view of computing resources. The use of a core model is possible in the case of determining the mechanical characteristics of a tubular concrete column as a core structure. To determine the longitudinal and bending stiffness of columns, it is proposed to use a spatial solid-state model that allows for the joint operation of all these elements. According to the calculation results, the most loaded element is determined, that is, a steel shell pipe. It is shown that the loss of stability of the column as a separate element is impossible with such a configuration of the cross section.
