This paper deals with the experimental and analytical study of the rocking response of a free-standing block subjected to horizontal base excitation. Using blocks and base conditions of a plate without and with a slip-proof sheet, experiments were performed for both the free rocking and harmonic excitation tests. Experimental results of the rocking test are applied for evaluating the coefficient of restitution, which could be used to determine the reduction of angular velocity at the moment of impact between the body and the base. The coefficient of restitution obtained from the results of the free rocking test is used in the simulation. A piecewise-linearized equation is used for the numerical calculation by applying a newly developed algorithm to attain high accuracy. The results of the calculation are compared with those of the harmonic excitation test.
