휨-전단 파괴하는 강섬유 보강 고강도 띠철근 기둥의 거동특성

초록

The purpose of this study is to investigate the behavior characteristics of steel fiber high strengthRC tied column controlled by both flexure and shear. As a result, the displacement ductility ratioincreased about 31% compared with the non - reinforced specimens. The plastic hinge length wasevaluated by judging the length of the area where the average curvature of the cross sectionexceeds the yield curvature as the plastic hinge length in a section experiencing twice the yielddisplacement proposed by Priestley. As a result, FSFC-0 had a plastic hinge length of 188mm andFSFC-1 was 453mm. Therefore, it is shown that ductility of the structure is ensured by addingsteel fiber even in the flexure - shear failure column.
