摘要

Progressive collapse is the process of extensive failure initiated by local structural damage, or a chain reaction of failures. Local damage that initiates progressive collapse is called initiating damage. The main focus of this research paper is to assess the vulnerability to progressive collapse of atypical RC framed structures under column removal scenario using ETABS software having version v16.2.1. A G+9 RCC hotel building (finite element model) has been considered and designed as per Indian Building Code and Pushover analysis (nonlinear static analysis) was carried out. Then the removal process of the identified critical columns is initiated for progressive collapse to happen and the various parameters like Demand capacity ratio and Robustness indicator are calculated and then checked against the acceptance criteria as provided in GSA 2003. Thus the influence of removal of critical elements has been discussed here by comparing the parameters before and after the progressive collapse..
