A small, modern five-story office building collapses. This could be considered which type of collapse?

In assessing a five-story office building that collapses, the categorization of the collapse as a "heavy collapse" is appropriate. A heavy collapse typically refers to structural failures in buildings that are substantial in size and complexity, often involving multiple floors and significant weight. Given that a five-story building has considerable mass and structural components, this type of collapse poses a serious hazard not only to the structural integrity of the remaining components but also to the safety of any personnel who may be in or around the building during and after the collapse.

A heavy collapse can result from various factors, including design flaws, material failure, or extreme loads that exceed the building's capacity. The considerable height and design complexity of a five-story structure amplify the risks associated with such a collapse, as the potential for substantial debris and the possibility of secondary collapses or significant structural hazards increase.

In contrast, other types of collapses, such as basic, light, or moderate collapses, would typically involve smaller structures or less severe failures that do not carry the same level of risk or consequence. A small building or single-story structure would more likely fit into those categories, as they are generally less complex and have less weight. Thus, defining the collapse of a small, modern five-story office
