This method has more advantage compared with previous proposed other seismic retrofitting methods that is not necessary to install the braces because CES frames in themselves have excellent seismic performance. The purpose of this study is to investigate the seismic performance of RC frames retrofitted with CES frames, particularly to examine the behavior of unified sections of the existing RC and the strengthening CES. The dynamic load testing was carried out on four frame specimens, one RC frame and three retrofitted RC frames, with the experimental parameter of the amount of anchors used to connect the CES members to the RC members. This paper outlines the experimental program. The test results showed that the seismic retrofitting method by attaching the CES member to RC member improved the seismic performance of the frames. It was observed that there is almost no gap at the connection between CES member and RC member until large deformation. In addition, the ultimate strength of the retrofitted frame from the experimental results showed a good agreement with the calculated ultimate strength.
