The sliding bearings are used for lightweight structures instead of the laminated rubber bearings. In many studies, the frictional coefficients of sliding bearings are assumed as less than 0.1. However, even if frictional coefficient is about 0.2, it may be effective for a big earthquake(max. acceleration > 200cm/s2). In this study, the effectiveness of sliding bearings made of surface-treated steel plates is examined under different conditions with an eccentricity, a pressure, an input wave and others. The reduction effect of response is proved by shaking table test, and the frictional coefficients are identified analytically.
