A contemporary review on progressive collapse

Abstract

This study provides a comprehensive review of the latest analytical and experimental research aim at better understanding the nature of failure propagation and identifying the mechanisms responsible for building collapse. The dynamic collapse of buildings is a serious concern that can be triggered by a range of mishaps, including fires, gas explosions, vehicle collisions, design and construction errors, and natural wear and tear. With the proliferation of complex, multi-functional tall buildings in recent years, safety and stability have often taken a backseat. Additionally, the paper examines various guidelines for preventing collapse, focusing on the role of member action and corresponding material and section sizes in either promoting or hindering the spread of collapse. This study considers several control mechanisms that can be implemented to limit the area of influence following a local failure, thereby reducing the likelihood of a full building collapse. The study concludes that, addressing the risk of progressive collapse requires a multidisciplinary approach that considers structural design, material selection, construction practices, and maintenance procedures.
