One of the regular tests used for designing explosive materials for internal explosion is doing the explosion in a closed or partially closed environment to detect and analyzing the blast wave parameters. In this regard, the test so-called two- room test is considered among researchers. The test is performed in two reinforced concrete- built rooms which are connected by a door. The explosive material is detonated in one room and the effects of that are measured and analyzed in both of them. The purpose of the current study is to predict the maximum number of explosions which leads to destruction of the prefabricated rooms. Hence, after validation of the solution, the numerical simulation of the successive explosions was performed by AUTODYN hydrodynamic software. The damage parameter in RHT model of concrete was used as a basis to determine the number of allowable explosions. According to the mentioned basis and with extrapolating the simulation results, maximum number of the allowable explosions was determined for different amount of explosives.
