Abstract
In recent decades, the need for tall towers with different uses has increased day by day. The proper performance of these towers against earthquakes is of great importance due to the volume of investments and their residents. In high-rise structures, one of the problems that makes it difficult to use the structure is the high displacement values ​​of the floors, including the roof of the structure. Therefore, in this study, by calculating the values ​​of floor and roof displacement and comparing it with the allowable structural values, the need to use new methods such as long braces, truss belts and seismic isolation system is investigated. In this paper, first, using a selected laboratory sample from the frame, how to model and validate the results of nonlinear static analysis in the SAP software is discussed. Then, by modeling the 18, 22, 26 and 30 floor samples and performing nonlinear and dynamic static analysis of nonlinear time history, the seismic performance of the system has been investigated. And their behavioral curves are presented. Finally, the results of comparing seismic parameters and displacement values ​​in different samples are presented. The results indicate poor bending system performance in high-rise structures, making it difficult to use the building normally.
