Abstract: The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations of motion, the Hybrid Frequency Time Domain procedure, is used to compute the earthquake response of concrete gravity dams including the nonlinear sliding behavior and the frequency-dependent response of the impounded water and the flexible foundation rock. As an example, the earthquake-induced sliding response of a typical concrete gravity dam is computed to illustrate the nonlinear behavior.
