Probabilistic progressive collapse analysis of steel frame structures against blast loads

•A new probabilistic assessment framework is proposed to evaluate the failure probability of structures under blast loads.•The accuracy and efficiency of the proposed framework is verified by the direct Monte Carlo simulation method.•Collapse risk of a 10-story steel frame under VBIED is analyzed.•T...
