Description Three-Dimensional Earthquake Analysis of Concrete Dams. EACD-3D-96 implements an analytical procedure for the 3D analysis of earthquake response of concrete dams including the effects of dam-water interaction, water compressibility, and reservoir boundary absorption due to alluvium and sediments at the bottom and possibly at the sides of actual reservoirs. The flexibility of the foundation rock is included together with inertia and damping effects. The dam and fluid domain substructures are modeled by 3D finite elements; however, the foundation rock region is modeled by boundary elements on the surface of the canyon along the dam-foundation rock interface. The analytical procedure underlying the program assumes linear behavior for the concrete dam, impounded water, and foundation rock. Thus the possibilities of concrete cracking, opening of the dam construction joints during vibration, and water cavitation are not considered. The overall efficiency of the dynamic analysis procedure lies in representing the dam, the impounded water, and the foundation rock as three substructures of the complete system, with appropriate idealizations for each; and in a dramatic reduction in the degrees of freedom by transforming the displacements of the dam to generalized coordinates. It can be used to analyse the earthquake response of arch dams or concrete gravity dams with keyed contraction joints.
