Abstract

The performance-based design method has received the attention of researchers and engineers in recent two decades. In this regard, different methods have been proposed by the codes to design and assess the performance of structures. The main purpose of this study is the evaluation of the Iranian seismic code's efficiency. For this research, three 1, 5, and 10-storey buildings having moderate concrete moment frames are designed based on the criteria of the Iranian code. Then, the seismic performance of these structures is evaluated according to the yield point spectrum (YPS), ATC-40, and Iranian seismic rehabilitation instructions method through nonlinear static analysis. There are two different approaches in the YPS method which include evaluating the performance point location relative to the performance boundary and comparing the response modification factor demand with the one used for design. However, ATC-40 and Iranian seismic rehabilitation instructions methods evaluate the structure’s response at the performance point and target displacement, respectively. Results showed that the studied structures satisfy life safety performance levels according to the YPS and Iranian seismic rehabilitation instruction methods, while the 10-storey building satisfies the immediate occupancy performance level based on the ATC-40 criteria. Moreover, in the case of the examined structures, the Iranian seismic rehabilitation instructions are more strict than the other methods and the buildings designed based on the Iranian codes are evaluated as seismically safer based on ATC-40 and YPS in comparison with the Iranian seismic rehabilitation instructions.
