Abstract: The developments in construction make it compulsory for architects to plan the high rise structures in RCC. Unfortunately due to some reasons like gas explosion, terrorist attack, fire etc. high rise structures undergoes some major component failure. As the major component fails, sometimes part of the structure or whole structure tends to collapse. This behavior of the structure is called as progressive collapse. Progressive collapse may be a chain reaction of failures that circulates either throughout or some of the structure lopsided to the first local failure. The progressive collapse of building structure is commenced when one or more vertical load carrying members are removed. One of the important characteristics of progressive collapse is that the final damage is not related to the initial damage. In this project it is proposed to carry out progressive collapse analysis of regular and irregular structures. Structural model of building has been fashioned din ETABS and loads are applied as per GSA guidelines, for evaluation of progressive collapse nonlinear static method of analysis has been used. The analysis is done using ETABS 18 software and using codes of analysis, IS 1893: 2016, IS 456: 2016. Joint displacements, axial force, bending moment are evaluated. In all cases progressive collapse of internal column is more critical as compared to other cases.
