Abstract: In this paper, to study preventive ways against incidents involving the impact of steel plate concrete (SC) structures, the steel plate concrete (SC) walls composed of surface steel plates, tie-bars, shear studs and concretes were selected as the object of investigation. The impact analysis of the walls was performed using ANSYS/LS-DYNA, the FEM code, based on the force vs. time-history analysis, in which a series of numerical sensitivity studies were conducted to evaluate the effect of several parameters affecting the behavior of the SC wall. These parameters include the thickness of the wall, the thickness of the steel plate, and the diameter and space of tie bars. The results show that they all have an effect on the impact resistance of the SC wall. This is especially true with the thickness of the wall and the steel plate, and the spacing distance between the tie bars. These studies will serve as guidance and reference for the design of SC structures that are to be used in nuclear power plant buildings.
