In the present paper, effects of incoherency and wave-passage on nonlinear responses of concrete arch dams wereinvestigated. A double curvature arch dam was selected as numerical example. Reservoir was modeled as acompressible material and foundation was modeled as a mass-less medium. Ground motion time-histories wereartificially generated using Monte Carlo simulation approach. Four different FE models were considered including;Uniform excitation; Incoherence effect; Wave passage effect and; finally both incoherence and wave passage effects. Itwas revealed that modeling multiple-supports excitation could have significant effects on the structural response of thedam by inducing pseudo-static effect. Also, it was concluded that coherency effect overshadow wave passage effectand results obtained from non-uniform exciting of FEM including wave passage effect is close to the results of the FEmodel exited uniformly.
