Abstract

A Green element method (GEM)-Finite element method (FEM Combination (GEM-FEM) is applied to calculate hydrodynamic pressures arising from fluid- structure interaction in a reservoir impounded by a dam. The radiation condition for an infinite reservoir is efficiently handled by GEM. Some examples demonstrating the efficiency and utility of this GEM-FEM numerical combination are presented, 1 Introduction The interaction of gravity dams with water is highly influenced by the hydrodynamic pressures generated on the upstream face. The study of this effect will facilitate a general understanding of the pressures ^displacement and stresses that accompany a fluid-structure interaction between a dam and an impounding reservoir. In addition the results so obtained will provide a quantitative information concerning the response of a structure to different mod
