The one-degree vibration-sliding model which consists of mass, spring with dashpot, and slider is defined, and its vibration and sliding response to base earthquake shaking was numerically analyzed. First, a fundamental response of the vibration-sliding model was examined under the uniform sinusoidal base shaking, and the significant effect of its natural frequency on the response is explained. Then, the response of the vibration-sliding model was examined under irregular earthquake base shaking. And it was found the relationship of the residual sliding of the mass with the natural frequency can be summarized in a kind of response spectrum, which may be used for the estimation of the residual sliding after earthquake.
