Investigation of Nonlinear Behavior of Concrete on Seismic Performance of an Arch Dam Using Finite Element Method
Abstract: In this paper the
effect of nonlinear behaviour of concrete is investigated on seismic
performance of a double curvature concrete dam.
The Morrow Point concrete dam has been selected as the case study and
dam-reservoir-foundation interaction considered in the model. Finite element
method has been used for modelling and analysis of case study by applying the
El Centro earthquake components considering nonlinear behaviour of concrete.
The obtained results of nonlinear dynamic analysis illustrate the increasing of
displacement of dam crest along the river and decreasing of maximum principle
stresses in critical points. The results demonstrate the importance of
consideration of nonlinear behaviour of material in seismic performance of arch
dams to achieve the optimal design of models.
