000010726 520__ $$2eng$$aA procedure is developed for the earthquake response analysis of dam–reservoir-foundation system. The arch/gravity dam and a near filed foundation region are modeled with finite elements (FE), while the infinite fluid domain and the unbounded foundation are modeled with scaled boundary finite elements (SBFE). SBFE can be coupled seamlessly with FE and only the interface with FE needs to be discretized. The effects of water compressibility and reservoir boundary absorption on the earthquake response of an arch dam have been investigated for a wide range of wave reflection coefficient. It was found that reservoir boundary absorption introduces an added damping to the dam-reservoir-foundation system and reduces the hydrodynamic pressure on dam face considerably. Inclusion of water compressibility and reservoir boundary absorption is essential to predict the earthquake response of arch dams and to evaluate the earthquake safety of existing dams.
