Abstract

In this paper, a detailed validation of dynamic block is carried out by extended Discontinuous Deformation Analysis (DDA). A rigorous analytical model for a rigid block supported through a frictional contact surface on a horizontal or an inclined plane is proposed in which ground shakings are applied on base block or dynamic block in direction of either horizontally or parallel to the inclined plane, with or without a simultaneous vertical component of motion. Both analytical solution and DDA simulation results for 6 cases (block on an inclined plane, subjected to only-horizontal or horizontal-and-vertical seismic force, and excitation applied on base block or dynamic block) are presented. Two idealized wavelets and one group of accelerograms are used as excitation. Comparisons of the theory solution and DDA results for different cases are carried out. The Results show that DDA can simulate the movement of dynamic block successfully and give accurate results.
