Abstract
This paper discussed the effect of the integrated sliding bearing system on reduction of earthquake response of bridges. This system consists of the supporting rubber plate to support the main load such as the dead load and the live load, and the slider-buffer system to reduce the earthquake response. The static loading tests showed that more than 230% shear deformation resulted in stiffness hardening phenomenon, and 330% shear deformation destroyed the buffer. The sinusoidal vibration tests and the pendulum weight collision tests showed the friction coefficient of 10-25% in relation to the loading speed. The design procedure of this system was also discussed.
