Nonlinear finite element dynamic analyses were conducted for the RC walls subjected to hydrogen explosive load in order to verify an applicability of the analysis method by comparison with experimental results obtained from past explosion tests. The analytical results show good correspondence with the test results. It is concluded that the nonlinear response of the walls subjected to the hydrogen explosive load can be estimated by the finite element model with sufficient accuracy. Furthermore numerical study was carried out with various wave forms of the explosive load. As results, it is found that the maximum displacement in the nonlinear response was not influenced on by the wave forms, but depends on the impulse of the explosive load. It is also found that negative pressure of the explosive load is needed to be considered to evaluate the maximum wall response accurately.
