The article is devoted to topical issues of researching structural designs of multi-story buildings. Designing high-rise buildings of any purpose begins with solution of the main task - choosing a structural system based on functional and technological requirements. The choice of the structural system determines the role of each load-bearing structural element in the three-dimensional structure of the building. Conditionally, all structural systems can be divided into four main types: I – framework type; type II - framework with stiffening diaphragms; type III – tube system; IV - box (shell) type. Combined designs have greater structural flexibility due to the possibility of distributing parts of the loads by varying the rigidity of the load-bearing elements. In accordance with load distribution, high-rise building braces are divided into horizontal and vertical. Horizontal braces provide formation of hard discs in high-rise buildings, which distribute external forces among their elements, reduce bending moments, and prevent the frame from torsion and coming out of the plane of the elements. Vertical braces give rigidity under the action of horizontal loads on the vertical building elements connecting the floor discs.
