An Overview of Progressive Collapse
Aut hors Ketul Ruparelia Student, CEPT Univ ersity Dr. P V Patel Professor, Nirm a Univ ersity Bhairav Patel Structural Engineer, VMS Engineering Abst ract Progressiv e collapse is spread of an initial local structural dam age causing partial or total collapse of structure. It is a kind of chain reaction where local dam age of prim ary load carry ing elem ent causes the collapse of adjoining m em bers which in turn, leads to additional collapse. The ultim ate collapse is disproportionate to the original cause. In today ’s fast growing infrastructure trend, it is necessary to accom m odate the m ost unfav orable situations in structure design. At the sam e tim e it is equally im portant to m ake it financially v iable. Progressiv e collapse is a situation which can be triggered from any kind of abnorm al loading or ev ent like v ehicle im pact, bom b blast, design or construction error etc. Failure of any load carry ing structural m em ber can lead to catastrophic failure. In present literature study , an attem pt has been m ade to cov er the basic aspects of progressiv e collapse like historical background, m echanism , dev elopm ent of guidelines etc.
