Seismic Response of Trapezoid Shaped Dam: Dynamic Analysis in Consideration of Deformation of Foundation

Abstract

Using the two-dimensional finite element model including both trapezoid shaped dam body and its foundation as elastic body, analysis of stress and deformations of dams during earthquake were carried out. On the basis of these results, the effects of dam shape and deformability of foundation on dynamic behavior of dam body were discussed. And the differences between these results and analytical results where only dam body was modelled were also discussed.
