In this paper, a simple column base system in steel structures is proposed and the structural performance is experimentally examined. The column base is encased by filling steel fiber reinforced cementitious composites. In the test, cantilever column specimens are employed for both the proposed system and the ordinary column base embedded in normal concrete base, and cyclic load is applied. The results show that the specimens of proposed system give relatively ductile hysteresis characteristics for the limit drift ratio of 0.01-0.02(rad) in comparison to the specimens of the ordinary column base. It is concluded that the proposed simple column base system is applicable.
