Progressive collapse simulation is the latest challenge facing today’s engineers wishing to assess the integrity of structures and to develop any necessary progressive collapse mitigation strategies. To this end, an ideal progressive collapse numerical simulation should include the involvement and integration of the following elements: a modeling of the structural, non-structural components, and the load threat, the separation of parts, as well as the possible collision resulting from falling debris.
