This study performed a set of shaking table tests to analyze seismic response of base isolated structure in accordance with the type of the isolators. The base isolated structure is made of 100 ton concrete block to reflect effect of inertia by superstructure mass, and supported by 3 types of base isolated systems including LRB, EQS and FPS. Seismic response test on the base isolated structure was performed and behavior characteristic of each base isolated system was analyzed. As a result, while there was difference in response pattern by incident seismic wave, decrease of acceleration by EQS base isolated system was the largest while displacement was the lowest.
