This investigation deals with the rocking response of a rigid block subjected to 1-dimensional harmonic excitations with minute changes of system parameters, for example, frictional coefficient, the restitution coefficient, the amplitude of the horizontal excitations, and so on. In the past studies, it is obvious that the rocking system has very strong nonlinearity and various system parameters affect its behavior characteristic. One of them, the frictional coefficients between rigid block and base significantly affect the rocking motion and the distribution of rocking responses. In addition, the sliding displacement or the elasticity of the block and base cause minute changes of system parameters. Considering its effect is essential for rocking motion with very sensitive to minute changes of system parameters. In the numerical program, the minute changes are produced by random numbers of normal probability distribution.
