A Experimental Study on Concrete Filled Tubes(CFT) in Flexure

충전강관 부재의 휨거동에 대한 실험적 연구

To apply CFT members into the bridge girders, bending behavior of CFT is to be investigated. However, pure bending tests of CFT have been rarely performed, while much of the experimental study of CFT focuses on the axial loading. In this study, ultimate bending strength of CFTs with various different thicknesses and diameters was measured and compared with behaviors of bare tubes. It shows the beneficial effect of concrete for CFT in flexure to increase strength and ductility.
