The purpose of tIn this study, the column removal scenarios defined by U.S. General Services Administration (GSA 2003) were performed to compare the progressive collapse resistance of ordinary moment frames (OMFs) to that of intermediate moment frames (IMFs), which are most frequently used in the design of steel structures. Three prototype structures with either welded unreinforced flange-bolted web (WUF-B) or reduced beam section (RBS) connections suitable for each of the lateral load resisting systems were designed according to KBC 2016. Considering the reliability, convenience, and efficiency of modeling and analysis, structural members (beams, columns, connections, and composite slabs) were modeled using reduced models of 1-D and 2-D elements, and energy-based approximate analyses reflecting dynamic effects were performed. The comparison of the progressive collapse resistance capacities of the buildings was based on GSA 2003, as well as the structural robustness index. All three structures satisfied the chord rotation criterion of the GSA and showed sufficient resistance capacities in the 1-column removal scenario (1-CRS), but not in the 2-column removal scenario (2-CRS). In addition, it was confirmed that the RBS connection showed better resistance capacity than the WUF-B connection in results produced by the OMFs, and that the OMFs were superior to the IMFs when comparing the structural systems. Using these results, it is possible to reduce the effort needed for complex numerical modeling and time-consuming analyses and to aid in predicting the progressive collapse resistance capacity of similar types of structures.
