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.
