The recent progressive collapse analysis method of structures assumes the threat-independent removal of vertical load-carrying elements. In reality, a blast-induced column-missing event will produce the damage on adjacent structural elements and the rapid dynamic response of the structures. In this study, the strain rate effects on the dynamic collapse behavior of blast-damaged steel moment frames are investigated by performing the blast-induced sequential progressive collapse analysis of a three-storey steel moment frame.
