The dynamic response of prestressed concrete slab under blast loading was analyzed based on LS-DYNA. The laws of influence of degree of prestress, combined reinforcement index, weight of explosives, thickness of slab on the dynamic response of prestressed concrete slab under blast loading were discussed, and the failure modes were given. The analysis results showed that the peak displacement at mid-span increased with increasing of degree of prestress and weight of explosives, and reduced with increasing of combined reinforcement index and thickness of slab. All the parameters, the influence of weight of explosives on displacement response of slab was significantly. Rationalization proposals were provided for blast resistant design of prestressed concrete slab.
