Survey Paper on Progressive Collapse of Multistory Steel Building

The term Progressive collapse is defined as a situation where local failure of a primary structural component leads to the collapse of adjoining members, which in turn leads to additional collapse. Hence, the extent of total damage is disproportionate to the original cause. Progressive collapse can be triggered by manmade, natural, intentional or unintentional causes. Furthermore Prevention to the progressive collapse is carried out by Alternate load path, Tie forces, integrity provisions, and finite element model. They provide redundancy to the structure to mitigate collapse. The study of analytical approaches for evaluating progressive collapse is carried out by linear static analysis using Alternate Path Method recommended in the General Service Administration (GSA) guidelines is presented in the work. For this work we have considered multistory steel building (G+10) located in seismic zone III. The objective of this work is to study the vulnerability of Steel frame towards progressive collapse and also prevention of progressive collapse of Steel frame by using linear static analysis. This analysis is carried out by columns removed condition.
