抄録: In order to establish a rational impact design procedure of column type of RC rock-sheds, impact response analyses of the rock-sheds by means of LS-DYNA3D were compared with the results obtained from a demonstration impact test which was conducted by using Tateiwa Zuido near Matsumae in Hokkaido. The dynamic responses of the RC rock-shed using two types of absorbing system: 90 cm thick sand cushion and Three-Layered Absorbing System (TLAS), were considered. The results obtained from this study are as follows: 1) the elastic impact behaviors of column types of RC rock-sheds can be predicted by using LS-DYNA3D code with some safety margin for types of absorbing system; 2) the conventional design procedure for the type of RC rock-sheds may overestimates sectional forces the against falling rocks along the transverse direction, but underestimates the case of falling rocks near RC columns.
