Seismic isolation systems including Laminated Rubber Bearing(LRB) and Friction Pendulum System(FPS) have been being used to improve the seismic performance of bridge structures. This paper studied the seismic load reduction effect of a steel slag-based seismic foundation isolation system by using 1-G shaking table tests. The result shows that ground acceleration reduces significantly through soft clay ground to the foundation isolation system, and it further reduces through the foundation isolation system. Numerical analyses show similar results. These results show that the seismic foundation isolation system is effective in seismic performance improvement of bridge structure.
