In this study, the response of arch dams is obtained for in-phase and anti-phase ground motions when there is no water in the reservoir. The material of the dam is considered to be linearly elastic, homogenous and isotropic. The foundation and banks of the dam, which are usually of hard rock, are assumed to be rigid. The S16E component of San Fernando Earthquake, February 9, 1971, has been used in the calculations. The response of arch dams determined for anti-phase dynamic effects is compared with that of in-phase (uniform) dynamic effects.
