Many researches have been performed for evaluating local damage to reinforced concrete (RC) structures caused by perpendicular impacts of rigid projectiles. Up to now, few impact tests oblique to the target structures have been carried out. This study has been conducted with the purpose of proposing a new formula for evaluating the local damage caused by oblique impacts based on previous experimental and simulation results. In this paper, the results of simulation analyses for evaluating the local damage to a RC panel subjected to normal and oblique impacts by missiles, by using the analytical method that was validated using the results of previous impact experiments. Based on the results of these numerical analyses, the effects of the rigidity of the missile as well as the impact angle on the local damage to the target structures are clarified.
