H-SHAPED STEEL BEAM
To provide an H-shaped steel beam that can expect local buckling stiffening effect of flanges in addition to stiffening of a web, and excellent in deformability after maximum proof stress.SOLUTION: An H-shaped steel beam 1 according to the present invention is the H-shaped steel beam 1 that has an upper flange 3, a lower flange 5, and a web 7 connecting the upper and lower flanges 3, 5, and where an orthogonal cross section in a longitudinal direction has a H shape and a beam end portion is stiffened by stiffening members 11. The stiffening members 11 comprise: upper stiffening members 11a that are disposed orthogonal to a beam longitudinal direction, and attached to the upper flange 3 and the web 7; and lower stiffening members 11b that are spaced apart from the upper stiffening members 11a by a predetermined distance, provided on the virtual straight lines L continuing to the upper stiffening members 11a, and attached to the web 7 and the lower flange 5.SELECTED DRAWING: Figure 1
【課題】ウェブの補剛に加えて、フランジの局部座屈補剛効果が期待でき、最大耐力以降の変形性能に優れたＨ形鋼製梁を提供する。【解決手段】本発明に係るＨ形鋼製梁１は、上フランジ３と下フランジ５とこれら上下のフランジ３、５を繋ぐウェブ７を有し、長手方向直交断面がＨ形で、梁端部が補剛部材１１によって補剛されたＨ形鋼製梁１であって、補剛部材１１は、梁長手方向に直交して配置され、上フランジ３とウェブ７に接合された上補剛部材１１ａと、上補剛部材１１ａと所定の間隔を離して、かつ上補剛部材１１ａに連続する仮想直線Ｌ上に設けられて、ウェブ７と下フランジ５に接合された下補剛部材１１ｂとを備えてなることを特徴とするものである。【選択図】 図１
