Earthquake investigation and earthquake resistance design of dams is of real significance in light of the calamitous outcomes if such a structure is to fall flat. In India we don't have any rules to check the seismic burden for the investigation of Dam. Without any very much characterized method, design workplaces for the most part utilize an experimental method which does not consider the dynamic properties of dam and diverse earthquake zone. This study is an endeavor to create rules to consider seismic power for the examination of solid gravity dam. A proportional static method for seismic design of solid gravity dam is created considering the dynamic properties of the dam and in addition diverse earthquake zones. For this to accomplish, a group of solid gravity Dam with shifting stature, base-width and side slope is broke down utilizing finite element programming ANSYS. Dams are demonstrated with 2-D plane strain elements. Dynamic properties of all the chose dams are assessed. A relapse examination is done on the modular properties acquired from the finite element investigation keeping in mind the end goal to create observational connection between era, tallness and base width. The base number of modes that must be taken into for the examination is chosen by considering the mass cooperation proportions. Design base shear is figured by utilizing the Design flat increasing speed range quality and Seismic weight of the building. A method is proposed to disseminate the figured base shear over the stature of the Dam.
