In order to understand rocking vibration characteristics of a small structure installed on the seismic isolation system using sliding mechanical system under various condition, we have proposed a numerical analysis model considered non-linerity for the restitution coefficient in collisions while rocking vibration between the small structure and the seismic isolation system using 2-DOF. In case of sine wave as an input, the phase of waveform and the rising of rocking vibration between the vibration test and the numerical analysis were good agreement.. And, in case of input wave using observed seismic ground motion, it was good agreement between waveforms in vibration test and results of numerical analysis. For these reasons, the model proposed in this study is effective to evaluate vibration behavior of the small structure installed on the seismic isolation system using sliding mechanical system.
