In order to establish a rational impact response analysis method for arch shape RC structures, conducting static and falling-weight impact loadings of small scale and arch shape RC beams, and three-dimensional elasto-plastic finite element analysis for those was performed and its applicability was discussed by comparing with experimental results. From this study, the following results were obtained: (1) impact force wave and maximum displacement at the loading point and the crack patterns occurred on the side-surface of the arch beams can be simulated in a good agreement with the experimental results; and however, (2) the damped free vibration after unloading and residual displacement cannot be better simulated.
