Abstract
Strong earthquake shaking may cause cracking of concrete gravity dams and threaten safety of the dams. Hence, possible cracking of a dam body must be studied carefully. In this paper, a coupled FE-BE method is developed for nonlinear dynamic analysis of a dam-reservoir system with rigid foundation. The possible cracking of a concrete gravity dam under intense ground shaking is analyzed to find effects of dam-reservoir interaction and added mass technique on the cracking of dam body, followed by discussion on effects of reinforcing bars on reducing the earthquakeinduced cracking. Through these, the present method is proved its validity.
