In order to establish a proper finite element model of prototype RC girder with sand cushion for impact response analysis, dynamic response analysis of RC girder with sand cushion subjected to falling weight impact force was performed to improve the state of the art of protective design for real scale rock-sheds by using LS-DYNA code. An applicability of proposed model was discussed comparing with experimental results (e.g. impact force, reaction force, and displacement waves). From this study, it is seen that the dynamic characteristics of impact response can be better simulated by using the proposed model.
