dc.description.abstractAn effective analytical model based on the hybrid FEM-DRBEM scheme has been developed to study the fluid-structure interaction and earthquake response of arch dam-reservoir systems. Applying the substructure technique, the finite element method is utilized to model dam structure and the dual reciprocity method is used to model the reservoir domain. Considering the bottom absorption effects, the reservoir domain is idealized as a finite region of irregular geometry adjacent to an infinite domain of uniform cross section. The three-dimensional dual reciprocity method is applied to model the finite domain of the reservoir. The uniform infinite domain is modeled by applying two-dimensional eigenvalue analysis based on the dual reciprocity formulations over the uniform cross section combined with a continuum expression in the upstream direction. Based on the model, a computer code has been developed to calculate the seismic response of a three-dimensional dam-reservoir system of arbitrary geometry to upstream-downstream, cross-stream and vertical harmonic ground motion. The model is verified by comparing the hydrodynamic response of a three-dimensional rectangular reservoir with that from the analytical formulation existing in the literature. The model was applied to investigate the hydrodynamic and structural response of the Karakaya dam-reservoir system. The effects of arch dam-reservoir interaction, the reservoir geometry and the reservoir boundary bottom absorption on the hydrodynamic and structural responses are studied.
