Application of 2d and 3d Finite Element Modelling of Gravity Dams Under Seismic Loading

Abstract

The Finite Element Modelling (FEM) is widely used in various type of analysis by numerous researchers and engineers worldwide. In present study, a challenge is made to consider dams under seismic loading deliberating hydrostatic effect of reservoir water using nonlinear dynamic analysis. Therefore, it tries to take deepest section of dams in 2 and 3 dimensions to show the effect of FE modelling during analysis. For this aim, Kinta Roller Compacted Concrete (RCC) gravity dam in Malaysia has been selected as case study and the bidirectional Koyna earthquake accelerations, 1967 are imposed to the dam. The outcomes show that the dam response is almost similar in terms of displacement and damage analysis under seismic loading, however, the stress responses are not same for different aforementioned models.
