     in this paper numerical study of behavior of simply supported rc slab subjected to blasting is presented. to accomplish this task, abaqus 6-12 software, capable of performing nonlinear analysis, were used. using available experimental data, and with a reverse engineering process, appropriate behavioral model for concrete, rebar and explosives were adopted and the detail of modeling was verified. after verification, the effect of explosion depth and charge mass, keeping constant the slab size and concrete grade were investigated. it was shown that increasing the explosion depths beyond 0.2 m leads to an increase in the damage on front and back surfaces and the crater in back surface while the crater diameter on the front surface decreases. it was also shown that the size of damage and crater increases almost linearly with increasing the mass of tnt, keeping the charge depth fixed.
