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.

The purpose of this study is to evaluate the seismic performance of the existing reinforced concrete frames with strengthening beam-column joints. The repairing and strengthening methods of RC joint are to inject the epoxy resin between the surface of concrete and covering PGpanels. As the experimental results, a specimen with strengthening beam-column joints showed more ductile behavior than a specimen without strengthening.

In this paper, the purpose is to confirm the dynamic Response characteristics of the base-isolated structure for shake table test and the validity of the envelope design method. For the purpose, this research was conducted in three different stages. First, a isolator(Rubber-Metal Laminated Bearing) and a damper(U-shape Steel Damper using SS400 or HTS) were designed based on the envelope design method which were applied to the two-story steel frame specimen. Second, the isolator and the damper were tested to confirm the shear-performances of them. And then, the analytical parameters of nonlinear time history analysis were set up based on the results of shear tests. Lastly, nonlinear time history analysis were conducted. As the result of the study, the high performances of the seismic isolation system and the validity of the envelope design method were confirmed.
