Progressive collapse analysis study of rc building:a review

Abhishek Jaiswal, Girish Joshi

Abstract


The progressive collapse of building is that the collapse of whole building or a part of building in progressive manner thanks to spread of local failure from element to element. thanks to progressive collapse there'll be severe loss of building and lifetime of humanity as progressive collapse happens suddenly. Toavoid the loss got to design a building by proper study and analysis of building for progressive collapse. thanks to earthquake, blast, vehicular sudden impact, etc if the column isn't capable to face up to sudden impact then column may get failed and due that other columns also get failed, which causes loss of whole structure. A linear static analysis and non-linear dynamic analysis using time history method is administered using finiteelement software. Two column removal eventualities particularly corner and middle column removal situation area unit thought of. In Linear Static analysis Demand capability Ratio(DCR)values and member acceptance criteria area unit thought of and Non-linear Dynamic Analysis (NDA)Time vs Displacement, most Axial force, bending moment results wherever the column is removed associate obsolete as base for comparison area unit calculated to know the potential for progressive collapse of a structure.

Key Words - RC frame buildings, Progressive, Linear Static, Non-linear Dynamic.
