Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. Currently the design guidelines for the prevention of progressive collapse were not available in Korea. The purpose of this paper is to evaluate the progressive collapse resisting capacity for RC flat plate system by comparing the Demand-Capacity Ratio(DCR) differences of the systems using the alternated load path method which is the guide line of GSA. The finite element method(FEM) analyses were conducted with the various variables that were the differences between Effective Beam Width(EB) model and plate element FEM(PF) model, the changes of seismic design category(SDC), the changes of layer numbers, and the beam locations in contiguous removal column. According to this study, the strength contributions of the slab in the EB models were underestimated relatively than those of the slab in the PF models by the results of linear static analysis. The EB model, extensively used in practical affairs, is useful for the analysis about the lateral load, but this model does not consider properly the load distribution effect of slab's to evaluate the progressive collapse resisting capacity. Hence, a detailed finite element method (FEM) analysis considering the slab element will be needed for progressive collapse resisting capacity of the flat plate system. From the analysis results, it appeared that the progressive collapse resisting capacity of the 10 storied buildings was similar to that of the 5 storied building in the SDC B, but the progressive collapse resisting capacity of the 10 storied buildings was more effective than that of the 5 storied building in the SDC D.
