鋼繊維補強セメント系複合材料を用いた鋼構造柱脚 : 接合高さ比0.75と0.65の応用モデルの破壊モードと変形特性

Abstract

In this paper, a simple junction 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 proposed system, and cyclic load is applied. The results show that the proposed system gives enough stiffness, strength and ductile hysteresis characteristics. In addition, a joint-spring model based on a mechanical model for the macroscopic shear failure of concrete is applied to the structural experiments, resulting in the good agreement between the experimental results and the analytical prediction.
