Behavior of Reinforced Concrete Panels by Impact of Hard Projectile

As the scale of infrastructures enlarges, the level of damages for human life and property due to the failure of structures keeps increasing, especially for nuclear power plants. Very severe damages can occur due to internal failures of plants by local effect of penetration, perforation, and scabbing developed by impact of projectiles at high velocity. Therefore, in order to prevent this severe potential hazards, accurate prediction of damage level by local effects is very important. For this accurate prediction, Impact experiment for structures is needed to evaluate accurately the behavior of structures by impact. In this research, impact experiments of hard projectile for reinforced concrete(RC) panels scaled from containment wall of nuclear power plant were performed. The results of impact experiment are discussed to evaluate impact behavior.
