Application of Pseudo-Symmetric technique for seismic analysis of concrete arch dams

Abstract

Damreservoir interaction can be treated by different approaches. One of the efficient methods available for time domain analysis is referred to as PseudoSymmetric technique. In the present study, a gravity dam example is considered to verify this technique. Subsequently, water compressibility effects on seismic behaviour of a typical concrete arch dam are studied. It is found that by considering water compressibility the maximum tensile stresses mat increase significantly which may lead to more severe damage during an earthquake.
