The objective of this study is to develop the reinforcing design method of the NPP (nuclear power plant)'s steel plate concrete (SC) wall for enhancement of impact resistance capacity under the aircraft and missile impact loading considered in the design of NPP's facilities. This study investigated the effects of the several parameters that can affect impact resistance capacity of SC wall using finite element analysis method.(e.g., thickness of concrete and steel plate, material strength of concrete and steel, and other reinforcing design method).
