SQUARE STEEL PIPE
PROBLEM TO BE SOLVED: To provide a square steel pipe excellent in cross-sectional efficiency, capable of equalizing or maximally enhancing even a section modulus and the second moment of area in the bending force action direction, while maximally enhancing a local part buckling stress degree of a surface (a compression surface part) of becoming the compression side when receiving bending force, while reducing the cross-sectional area, by specializing as a bending force-receiving member.SOLUTION: In a range of 15.6-200 in the plate thickness ratio of A/t, B/t, a shape of a corner part of the four corners is basically formed in a vertically asymmetric cross-sectional shape, in a mode of becoming larger than the corner length in the lateral direction of the lower side, particularly in the corner length in the lateral direction of an upper side corner part, that is, in a mode of (C>C).
【課題】曲げ力を受ける部材として特化し、断面積を小さくしながら、曲げ力を受ける場合に圧縮側となる面（圧縮面部）の局部座屈応力度を極力高くしつつ曲げ力作用方向の断面係数及び断面二次モーメントも同等ないし極力高くすることが可能な、断面効率のよい角形鋼管を提供する。【解決手段】板厚比Ａ／ｔ、Ｂ／ｔが１５．６〜２００の範囲において、四隅のコーナー部の形状を、基本的には上側コーナー部の特に横方向のコーナー長が下側の横方向のコーナー長より大きくなる態様で、すなわち、「ＣＢ１＞ＣＢ２」の態様で上下に非対称の断面形状とする。【選択図】図１
