This research deals with the nonlinear response behavior of rocking vibration associated with impact and sliding on the rocking motion of rigid block under two dimensional sinusoidal excitation of horizontal and vertical direction. The nonlinearities of the rocking vibration strongly depend on the impact between block and base, which should induce abrupt reduction in kinetic energy, and sliding motion which occurs during rotation and impact. Particularly, when the oscillation direction of base is varied, the rocking vibration as well as sliding motion are strongly influenced by the change of oscillation trajectory. The chaotic responses are observed in wider region, when the frequencies of each excitation direction are different. The complex behavior of chaotic response, in the phase space, is closely related with the trajectory of base excitation and the sliding motion.
