Abstract:Due to the rear-face steel plate of the steel plate concrete wall is very effective in preventing the perforation and scabbing of concrete, in order to resist the impact of commercial aircraft crash, Steel plate concrete (SC) structures are selected to be used in the design of external walls of nuclear island buildings for the new type nuclear power plant. In this paper, the FEM code ANSYS/LS-DYNA was used to simulate the re-sponse analysis of a Boeing 707-320 aircraft impact on a steel plate concrete (SC) containment based on the force time-history analysis method. The results show that even though in the condition of the Boeing 707-320 commercial aircraft impact load applied on the most adverse impact position of the cylinder containment, the response of the SC containment is small, in the other word, the SC containment can resist the impact. Fur-thermore, the increase of the thickness of the steel plate can effectively reduce the structural response to the impact.
