Abstract
In this paper, in order to accumulate basic knowledge for establishing the rational performance-based impact resistant design procedure of the RC type rock-sheds, casting a 2/5 scale model of RC type rock-shed, the falling-weight consecutive impact loading tests of the structure with sand cushion is conducted by using 10,000 kg heavy-weight. A heavy-weight is consecutively fallen onto the roof from 1 m through 10 m height. From this study, following results are obtained: 1) maximum impact force caused in the heavy-weight is in good agreement with that obtained by using a conventional equation; and 2) the center of the roof slab finally reaches the ultimate state in punching shear-failure mode.
