This paper discuss the progressive collapse analysis of RC frame building by removing different column one at a time as per the GSA guidelines. Building consists of 3 X 3 bays of 5 m in both direction and designed by Indian code as a special moment resistant frame. Structural model of building has been created in ETABS and loads are applied as per GSA guidelines, for evaluation of progressive collapse linear static method of analysis and nonlinear static method of analysis have been used. As per GSA guidelines, removal of three columns one at a time is studied, for Corner column, Exterior column and interior column at ground floor. For all three cases both linear and nonlinear analysis have done and DCR ratios are evaluated. Member having DCR ratio greater than 2 fails for corresponding column removal case. It is observed that shear in beam is not critical in any case, Columns are also not critical in Progressive collapse. But by Linear static analysis and nonlinear static it is observed that beams are going to fail in flexure.
