Progressive collapse is a series of failures that spread beyond the original local breakdown, either over the entire building or just a part of it. Building intended to withstand seismic events have good robustness against progressive collapse, according to study on the failure of structure due to progressive collapse. To evaluate its robustness, however no in depth studies have been done so far. So, the purpose of this research is to examine the potential resistance to progressive collapse of buildings with seismic design. In the present study high rise R.C.C irregular building with different types of irregularities has been analyzed with and without removal of column to find out critical column. The study is done with the aid of the commercial software ETABS. Various seismic parameters like maximum lateral displacement, story drift ratio, time period, overturning moment etc. has been compared.
