A Review Paper on Progressive Collapse Analysis of ultistorey RCC Building

The spread of an initial local failure from element to element resulting eventually in the collapse of an entire structure or a disproportionately large part of it, is called as progressive collapse. This review paper provides a comprehensive overview of the progressive collapse of multistorey Reinforced Concrete (RC) buildings, focusing on the causes, analysis methods, and mitigation strategies. The paper synthesizes current research and design guidelines from various codes, highlighting key factors influencing collapse resistance and the role of modern analytical techniques which will be helpful in the assessment of progressive collapse. It also discusses the critical aspects of load redistribution, structural redundancy, and ductility in preventing the severe events.
