Fire-induced collapse

Fire-induced collapse occurs when a structural element, such as a building’s steel or concrete components, weakens significantly due to high temperatures from a fire. The heat causes metals to lose strength and shape, while concrete can crack and spall, compromising the overall integrity. Once critical parts of the structure become too weakened, the entire building or sections of it may suddenly fall or collapse. This process highlights how intense fires can weaken and destabilize structures quickly, often with little warning, emphasizing the importance of fire-resistant design and effective firefighting measures.
