냉간성형 원형 및 각형강관부재의 인성에 관한 실험적 연구 - 폭-두께비를 중심으로 ( An experimental study on the strength and ductility of cold-formed circular and square steel members )

This paper is an experimental study on the member characteristics of cold-formed hollow section members(CHS and SHS) produced by two different manufacturing processes. On stub-columns under uniform compression, yield strength or ductility factors governed by local buckling have particular relationships with D/t or d/t rations. In this paper, in order to make clear the influences of D/t and d/t on the yield strength, maximum strength and plastic deformation capacity of hollow section members, compression test of stub-columns are carried out.
