Fortunately, structural collapse is a rare event, but it can happen due to a variety of potential triggers. "Progressive collapse" scenarios result in the extent of collapse within a structure being grossly disproportionate to the magnitude of the event that initiated it. This phenomenon has been observed in high-profile events such as the collapse of the Alfred P. Murrah Federal Building in Oklahoma City. Although cases of this magnitude are relatively rare, progressive collapse events that are less publicised also occur.

幸运的是，结构性倒塌是一种罕见的事件，但它可能由于各种潜在的触发因素而发生。“渐进式倒塌”情景导致建筑物内的倒塌程度与引发倒塌的事件的严重程度严重不成比例。这种现象在诸如俄克拉荷马州市阿尔弗雷德·P·默拉联邦大楼倒塌等备受瞩目的事件中已经观察到。虽然这种规模的情况相对罕见，但也发生了较少宣传的渐进式崩溃事件。
