      interaction of concrete gravity dam with foundation and reservoir is one of the most important subjects in analyzingseismic behavior of dams. this paper presents an experimental study on seismic behavior analysis of dams consideringthe interaction among concrete gravity dam, foundation and reservoir. herein,a scaled dam has been constructed withscale factor of 1:30 (model: prototype)and modeled with foundation and reservoir on shaking table. using differentsensors on critical points of the model and also inside the concrete dam, the interaction behaviorhas been investigatedduring a specific applied earthquake. in this regard, multiple parameters have been evaluated during the earthquake,including displacements, hydrodynamic pressurein upstream, variation of acceleration/pore-water-pressure from bottomlayers of foundation to free surface andfinally, variation of the soil dynamic responses beneath the dam.the results ofexperimental model are useable for verifying numerical models.
