Numerical Analysis of Dynamic Response of Concrete Gravity Dam under Blast Loading in the Reservoir

Studies about effects of blast in the reservoir on dynamic behavior of concrete dams is accelerated with began of Second World War and the necessity of finding the persevering ways of this structures against of blast loading (Cole, 1948). In the present paper the effect of explosion in the reservoir on dynamic response of concrete gravity dam is study using ABAQUS commercial software. In the present research two different gravity dam model are considered and the effect of geometrical and material properties on dynamic response of gravity dam are studied. In the first model the linear behavior of material and in the second model the linear and nonlinear behavior of material are considered in the analysis (Sprague and Geers, 2006).
