  • Steel ordinary moment frame(steel OMF) has been used as a seismic force resisting system in regions of low and moderate seismicity. In this study, the seismic performance of the steel OMFs with various heights in SDC $C_{max}$ was evaluated. For this purpose, nine steel OMFs were designed according to seismic design codes(ASCE/SEI 7-10, ANSI/AISC 341-10), and the collapse probability of these steel OMFs were estimated using FEMA P-695. The collapse probability of steel OMFs became larger with an increase in the height of frames. Some of steel OMFs designed according to current design codes did not satisfy the acceptance criteria specified in FEMA P-695.

  • The purpose of this study is to outline the analysis procedure for evaluating the performance of moment resisting steel frames. For this purpose, three ordinary moment resisting frames are designed in compliance to UBC 1994. The evaluation is performed by nonlinear static procedures using two analytical models. Only one analytical model using panel element can reflect the panel zone deformation explicitly. The limit values in FEMA 273 are used as guidelines of predicted demand parameters by which the performance of OMRFs may be assessed.
