摘要：

The present paper deals with a numerical computation using finite element method for concrete structures subjected to dynamic loads, usually of seismic nature the consequences of which are often devastating. In the general equation of dynamic, a law of concrete material behavior taking into account models based on the damage mechanics has been implemented. From a phenomenological viewpoint, the chosen behavior model takes into account the damage caused by the opening of micro-cracks. For numerical application, two dimensional seismic analysis of Koyna gravity dam is performed by using the 1967 Koyna earthquake records. The effects of damage on earthquake response of the concrete gravity dam are studied. (C) 2014 Published by Elsevier Ltd.
