application/pdf Usually RC rock-sheds are constructed by sequentially mounting 12 m long rock-shed units. Those units forming of rock-shed are independent and discontinuous to each. In order to establish a rational design method of RC rock-sheds, it is important to make the characteristics of dynamic response of the RC rock-shed unit under impact load at its arbitrary points clear. In this paper, the elastic impact responses on Sectional Forces of RC rock-shed units by means of DYNA3D are discussed. Assuming the load distribution area, the maximum sectional force are numerically analyzed when impact load was surcharged near the free edges of the RC rock-shed unit. The values for M_y and Q_y became almost twice and thrice than the values obtained when impact load was surcharged at the canter of the structure. A rational design procedure of RC rock-shed can be formulated considering the results obtained here. journal article
