The keyword LOAD_BLAST in LS-DYNA has been established to simulate the response of the structure under blast loading since V960. The ConWep algorithm in it is described in this paper. As the load and impulse computed by keyword LOAD_BLAST are smaller than those they should be, the accuracy and reliability of parameters in keyword LOAD_BLAST should be verified and adjusted according to the experiment results of the blast loading on blast door. The results show that the load and impulse computed by ConWep module in LS-DYNA will be close to the experimental results when the TNT equivalent in keyword LOAD_BLAST is multiplied by a factor of 1.35.
