Elastic sliding bearings are one of the most common seismic isolators used in Japan. The bearing’s hysteresis loop is typically bilinear in shape, and the mechanical characteristics are mostly determined by the friction coefficient. The dependencies of velocity and temperature on the friction coefficient should be considered to reproduce a realistic dynamic behavior for earthquake response analysis. To evaluate these dependencies of the elastic sliding bearings separately, a novel loading test plan with varying speed and temperature is developed and conducted. A numerical analysis method to distinguish two dependencies is also presented.
