Progressive collapse is a chain reaction of failure that relates local damage to large disproportional scale collapse in a structure. At present the research against progressive collapse focused on reinforced concrete (RC) and steel structures. This paper presented the state-of-the-art of study on progressive collapse of structures. A preliminary analysis on the progressive collapse of a typical planar composite frame with concrete-filled steel tubular (CFST) columns was performed using ABAQUS. Some general conclusions were given to refer for the further research on the composite frames.
