In order to contribute to the evaluation of influence of projectile impact to the interior component of nuclear facility, we have started research with purpose of grasping the properties of shock wave propagation in nuclear building and elucidating the impact response behavior of the structure. We conducted some impact response analysis and compared the results with the existing experimental data related to the RC panels subjected to projectile impact to confirm the validity of 3D FE model and numerical evaluation method. Then, the impact response of RC structure regarded as the wall structure, etc., of nuclear building was analyzed numerically using the validated 3D FE model and numerical evaluation method. In this paper, the influence of different stiffness of projectile on the impact response behavior of RC structure was investigated through the impact response analysis and the obtained knowledge from the results are presented.
