Abstract
Lateral forces, especially seismic forces, cause significant damage to structures, especially tall ones. On the other hand, sequence earthquakes also cause irreparable damage to structures. Therefore, post-tensioned connections are one way to improve structures' seismic behavior. This study investigated 12-story tall steel structures with simple flexural connections and post-tensioned connections in two dimensions and 5- and 8-story structures with simple flexural connections and post-tensioned connections in two dimensions under sequences earthquakes. In this study, the beam and column sections of the sarees mentioned above were designed with ETABS software and simulated with OpenSees software to apply sequence records. The previous simulation was validated, and the structures were analyzed non-linearly under sequence records. The results indicated that the maximum drift angle was reduced by 50% in the 12-story structure with post-tensioned connections. As a result, post-tensioned connections improved the behavior of tall structures.
