This pattern of continuous failure of structural members causes failure of whole structure.This phenomenon is called Progressive Collapse or progressive failure.When an abnormal load acts on the structure,then any one of the structural elements i.e.column,beam and slab are foremost to damage.Progressive Collapse Case Study - 3012 Words Internet The design of a building to resist progressive collapse may involve analytical methods that are not used in predictable design.The purpose of this project is to offer few concepts for design professionals to decrease the probability of progressive collapse of buildings in the event of irregular loading.It is not proposed as a design standard.Progressive Collapse and Seismic Performance of Twisted Hong (2011) estimated the progressive collapse potential of tilted irregular buildings,where it was observed that the performance of irregular buildings subjected to sudden loss of a column depends significantly on the location of the removed column.Among the irregularities of the vertical building forms,
