Abstract


Progressive collapse analysis of R.C frame building in this study is investigated by removing different columns at a time as per the guidelines of the General Services Administration of the U.S[7]. For this study,an eight-storied moment-resistant R.C building is considered. The building consists of a 4x3 bay of 98.4 ft. in the long direction (X-axis)& 44.28 ft. in the short direction (Y-axis) designed by the [2] code. The R.C frame building is modeled and analyzed for static analysis of progressive collapse using the structural analysis and develop finite element based software following GSA guidelines. Here three types of column removal cases are considered: removal ofthe corner column, exterior column& interior column. Then,the calculation of Demand Capacity Ratio (DCR) is considered for both beams and columns and checked for the acceptance criteria as per GSA. The obtained values of DCR indicate columns' safety and strong enough to resist progressive collapse and beams are not safe for progressive collapse for which beams need to be reinforced additionally.
