The numerical simulation for responses of reinforced concrete slabs under blast loads with the finite element program LS-DYNA was performed. A quarter of the three-dimensional solid model was established for the reinforced concrete slab. Blast loads were imposed on the surface of the slab. The H-J-C model for concrete was employed, taking into account the damage and the strain rate effect. The J-C model was employed to model the steel bar, taking strain effect into account. And the parameters of J-C model were derived by means of regressive analysis of experimental data conducted in our research group. The erosion technique was adopted to model the spallation process. The comparison result between numerical simulation and the test shows that the numerical simulation is an appropriate way for the study of responses of reinforced concrete components under blast loads.
