The article discusses issues related to the ratio of the stiffnesses of horizontal and vertical elements of high-rise buildings. Based on the principles of operation of the load-bearing systems of such buildings, the characteristic fracture points of the elastic vertical line curve are determined. The possibility of using expanded clay in floors is analyzed from the point of view of the influence of their rigidity on the deformation of the entire system. For various structural systems, displacements from the static wind load were calculated taking into account the pulsating component of the wind load, as well as a comparison of computer and manual calculations. The locations of automatic monitoring sensors are determined.
