Abstract
U.S. General Service Administration (GSA) published guidelines for the progressive collapse resistance of buildings in 2003 and 2013. There are significant changes introduced in the 2013 edition. The objective of this study was to compare the results of the progressive collapse analysis based on the 2003 and 2013 editions of GSA. For the purpose of the study, a 10-storey reinforced concrete frame building located in Vancouver, Canada was considered in the analysis. Progressive collapse analyses were conducted on a 3-D finite element model of the building in accordance with 2003 GSA and 2013 GSA, respectively. The differences between the two editions were also discussed in the paper, including the loads applied for the analysis and the acceptance criteria for the progressive collapse resistance. Finally, comments were made on the use of the 2013 GSA Guidelines.
