The purpose of this shaking table test is to evaluate the dynamic response characteristics of the base-isolated flat plate structure. For the purpose, the first one of two specimens was designed to specimen with shear band reinforcement and the other was designed to specimen using base-isolated system using the envelope design method which was applied to the flat plate structure specimen. The shaking table test was performed using El_Centro seismic wave(PGA=357m/s2). As the result of the test, the specimen using isolation system was predominant the response-reduction performance and energy absorption capacity than the other.
