Abstract
Distinct Element Method (DEM) is one of numerical methods which treat the area of object as a set of many stiffness elements and the deformation altogether by tracing the motion of each stiffness elements. This paper describes a basic study on DEM to dynamic behavior of fill dam during earthquake. Dynamic analysis are executed under waves which were recorded during earthquake, the damping constant are specified by applying the analytical results of the fill dam response acceleration. As a result of these, it is indicated that this non-linear spring model could estimate stress and displacement in a bank of fill dam adequately.
