Abstract
Gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape, mass and strength of the concrete. The purposes of dam construction may include navigation, flood damage reduction,hydroelectric power generation, fish and wildlife enhancement,water quality, water supply. The design and evaluation of concrete gravity dam for earthquake loading must be based on appropriate criteria that reflect both the desired level of safety and the choice of the design and evaluation procedures. The Dam discussed in this paper is of the height 110 m for which Equivalent static analysis and dynamic analysis by using time history method is carried out. Most of the organizations analyze the dams by elastic method which gives very rough results. Here Finite Element Approach is used to analyze the dam which is proved to be the realistic for such structures. A comparison is done between the equivalent static approach of seismic analysis with dynamic analysis by using time history. The dynamic behavior is studied by using Time History of actual earthquake of koyna (Maharashtra, India) and the proportioning is done to satisfy the stress limits.
