PROGRESSIVE COLLAPSE ANALYSIS OF AN RC STRUCTURE SUBJECTED TO SEISMIC LOADS IN SLOPING GROUND

Shilpa Shree G C, Syed Ahamed Raza

Abstract: Progressive Collapse is the spread of initial failure from element to element leading to entire collapse of an structure. It is due to vehicle impacts, fire,earthquakes and natural or man made hazards. Collapse leads to large proprtions of dispropriate triggers in the structures which makes structures incapable of withstanding loads and it leads to collapse of the structure. In this study special moment resisting frame of G+19 story building is modeled using FEM based software( ETABSV9.7). The analysis is carried as per GSA gudelines in zone V having medium soil by linear dynamic and non linear analysis. The story drift and story shears are calculated to know the potential for progressive collapse of an structure.
