In this study, the effects of inelastic beam-column joint, moment-resisting frame system and seismic design category on the progressive collapse resisting capability of structures are evaluated via nonlinear dynamic analysis for elimination of column following the procedure of GSA2003, where RC OMRF, IMRF and SMRF structures were designed in accordance with KBC2009. The bending moment-curvature relationship for beams and columns was identified with a fiber model, and the bending moment-rotation relationship for beam-column joints was calculated using a simple and unified joint shear behavior model and the moment equilibrium relationship for the joint. The results of the nonlinear dynamic analysis showed that framed structure designed with greater seismic load was evaluated to have higher progressive collapse resisting capability, and that the best progressive collapse resisting capability of structure was estimated in case of elimination of corner column, and that the analysis of 2-dimensional plane frame underestimated the progressive collapse resisting capability of structure due to negligence of lateral beams. |
