Progressive Collapse Study of Seismically Designed Low Rise Reinforced Concrete Framed Structure

In this study, linear and non-linear static analysis of low-rise models representing two-bay two-story three-bay three-story reinforced concrete framed structures designed as per Indian standard codes (IS 450:2000 IS 1893:2016) for the high seismic region using Envelope loading combination are assessed with without Guidelines U.S. (GSA) General Services Administration. The purpose study is to describe applicability Finite Element software in assessing behavior seismically low rise structure before after losing vertical structural element column considering dynamic increase factor, results indicate demand resistance ratios acquired from elastic hinge formation pattern obtained similar GSA combination, thus factor 2 recommended by Administration guidelines can be underestimated far progressive collapse considered, since both types combinations (in which one considers only normal design load path method while other alternate methods) acquire same type results, confirms does possess inherent property towards resistance. This provides a good example summary construction industry used engineers designing collapse-resistant structures.
