Inelastic response of a simple arch dam due to differential foundation movements

Abstract

Using ADINA, the inelastic response of a simple cylindrical arch dam of constant thickness and vertical banks due to differential foundation and abutment movements is analysed. Small displacements and strains are assumed. The mass concrete is idealized as an elasto-plastic material, where the yield stress in each element of the discretized dam is obtained from the biaxial failure envelope of concrete. A vertical ground movement is assumed, beginning at the centre of the arch and increasing linearly towards the abutment.
