In order to establish performance-based impact resistant design procedure for RC rock-sheds, falling-weight impact test of small Rahmen-type RC models with/without sand cushion was conducted. And its numerical simulation was performed by means of three-dimensional elasto-plastic finite element method and its applicability was investigated comparing with experimental results. The results obtained from this study are as follows: 1) absorbing effects of the sand cushion are significant but dynamic response characteristics of the model can't be much affected by sand cushion; 2) dynamic response characteristics of the RC model are similar to those under static loading; and 3) dynamic response behavior of the RC model under falling-weight impact loading can be better simulated by using proposed numerical analysis method.
