| Popis: | This paper reports a comparative study conducted on the non-linear performance of steel moment-resisting frame structures designed with the Iranian, European and Japanese seismic design codes of practice. To this end, typical three-, six-, nine- and 12-storey steel moment-resisting frames of the high-ductility category are designed based on the requirements adopted in the codes. The structural performance of each frame is then evaluated extensively based on Fema 356 provisions for life safety performance level utilising non-linear static procedure. Comparisons are made regarding the elastic stiffness, peak strength, target displacement, plastic hinge rotations of elements at the target displacement, sequences of hinging in various elements, global lateral response, as well as the total amount of materials used in each structure. Results reveal differences in global and local performances of the structures designed according to regulations relevant to each code. Moreover, in some cases, the requirements for life safety performance level are violated. Finally, recommendations are provided based on the results of the study. |
