Real building fires have highlighted the need for more large-scale structural fire research on steel-framed buildings. Investigations after these fires have shown when there is a compartment fire, the remaining cooler portions of a building will restrain the expansion of the heated members. This restraint can cause large plastic deformations in both the structural members and the connections. The fires have also demonstrated the ductility steel-framed buildings have during fires. This project provides videos of progressive collapse of steel buildings with exterior moment resisting frames (MRF) and interior rigid cores subjected to compartment fires, full story fires, and moving fires.
