The purpose of this research is to investigate the mechanical behavior of bare type column base connection in SRC structures damaged due to Hyogoken-Nanbu earthquake in Japan, and two series of tests were carried out. The first series is the flexural failure tests of column base. The second series is the shear failure, tests of column base. From the test results, it was shown that ultimate flexural strength can be estimated by the design code in AIJ Standard. On the other hand, ultimate shear strength can be estimated to proposed new evaluation method. In addition, it proposed an evaluation method for limit rotation angle of column bases. From the structural, tests and performance evaluation method, seismic performance of SRC columns using bare type column base were became very clear.
