COMPARISON OF SEISMIC RESPONSE OF GRAVITY odw DAMS BY DIFFERENT APPROACHES OF MODELLING OF RESERVOIR AND FOUNDATION

Abstract

The main aim of this study is to understand the Fluid-Structure interaction because it plays major role in the seismic analysis of darns. Different ways of modeling of reservoir and foundation can give variety ol behavior. This report gives the comparison of different l:i:ds of modeling of reservoir and foundation. Three different types of mode13 have been ana1yed by modeling of reservoir and Ibundation. Fouivia!ion is replaced with equivalent spring;. Even though added mass approach is most simple, it doesn't take consideration of fluid-structure interaction. Also in this study, the stability of the dam will be analyzed by two dimensional gravity method and Finite Element Method (FEM), using ANSYS 14.
