摘要

In this paper, a prototype model of reinforced concrete (RC) type rock-shed is numerically examined by means of three-dimensional elasto-plastic finite element based model of RC rock-shed structure, having sand cushion, against the impact of 10 ton heavy weight. This study is undertaken in order to improve the knowledge for establishing a rational performance-based impact resistant design procedure for the RC type rock-sheds. Following results are obtained from this study: (1) the model fails in the punching shear mode when surcharged at the center of roof slab; and (2) the impact resistant capacity of the free edges of the model is greater than that at the center, as the free edges can behave more flexibly and absorb more impact energy in comparison with the center of the roof slab.
