Abstract
Progressive collapse is a sudden, severe failure of a structure, spreading from an initial point of damage to other parts. It occurs when a critical component, like a column, is compromised, often triggered by accidents, explosions, or natural disasters. The concern about the progressive collapse increased during the late sixties after the Ronan Building incidences in the UK. Mitigation efforts against the progressive collapse focus on minimizing the risk and potential catastrophic consequences. The critical issue with progressive collapse is the significant difference between the initial and final damage, which can destroy the whole building. Various strategies prevent the initial damage from spreading and causing more destruction. These include strengthening certain load-bearing elements or designing the building plan more effectively. The General Services Administration (GSA) and the Unified Facilities Criteria (UFC) provide crucial guidelines for preventing progressive collapse. One standard method they recommend is the Alternative Path Method (APM). This method helps evaluate how a building would respond to potential progressive collapse by ensuring that the rest of the structure can still stand safely if one part fails. An attempt has been made in the current research to assimilate the research carried out in the recent past in the field of progressive collapse and its mitigation and put forth recommendations.
