This paper deals with rocking response behavior of rigid block structure subjected to horizontal excitation. A strict consideration of impact and friction between block and base is essential to identify the system parameters because the impact motion and sliding motion were influenced greatly by the rocking behavior. Therefore, not only restitution coefficient between block and base but also kinetic friction coefficient between those should be included in the modeling of rocking system. The program was developed to be able to simulate the responses of block subjected to simultaneous horizontal sinusodial excitations. By using this program, rocking responses were numerically calculated by the nonlinear equations for rocking system. From the results of response simulation and experiment the following results were obtained, the rocking responses are affected with impact motion due to restitution and friction and provide very complex behavior, the toppling condition of block is also influenced on the impact motion, and so on.
