SIMPLE COLUMN BASE SYSTEM OF STEEL STRUCTURES EMPLOYING STEEL FIBER REINFORCED CEMENTITIOUS COMPOSITE : Experiment on structural performance of basic model and applied model

Abstract

In this paper, a simple column base system in steel structures is experimentally studied. The column base is encased by filling steel fiber reinforced cementitious composites. In the test, cantilever column specimens are adopted for the basic and applied models of the proposed system and also the ordinary embedded column base, and cyclic load is applied. The results show that the applied model gives enough stiffness, strength and ductile hysteresis characteristics in comparison to the ordinary column base, and also the basic model gives relatively stable hysteresis characteristics for the limit drift ratio of 0.01-0.02 (rad).
