H-SHAPED STEEL AND COLUMN-BEAM JOINING STRUCTURE
PROBLEM TO BE SOLVED: To provide H-shaped steel and a column-beam joining structure of a beam and a column composed of this H-shaped steel, capable of avoiding early breaking of a beam flange in the vicinity of a joining part by stress concentration, without installing a stiffener on the column side in the joining part of the beam flange and the column, and without causing an increase in a steel material quantity.SOLUTION: A plate thickness of a central part 4 in the width direction of upper-lower flanges 2, is formed thicker than a plate thickness of both edge parts 5, and assuming a width of the flange as B, a plate thickness of both edge parts 5 as t1 and a plate thickness of the central part 4 in the width direction as t2, the ratio (t1/t2) of the plate thickness t1 to the plate thickness t2 is set to 0.40-0.77, and since a step difference caused by a plate thickness difference between the central part in the width direction of the flange and both edge parts is provided on the flange inner surface side, early breaking of the beam flange in the vicinity of the joining part by stress concentration, can be avoided without causing an increase in a steel material quantity.
【課題】梁フランジと柱の接合部において柱側にスチフナを設置することなく、かつ鋼材量の増加を招かずに、応力集中による接合部近傍の梁フランジの早期の破壊を回避することが可能なＨ形鋼およびこのＨ形鋼からなる梁と柱の柱梁接合構造を提供する。【解決手段】上下のフランジ２の幅方向中央部４の板厚が両縁端部５の板厚よりも厚く形成され、フランジの幅をＢ、両縁端部５の板厚をｔ１、幅方向中央部４の板厚をｔ２とすると、幅方向中央部の幅がＢ／３以下とされ、板厚ｔ２に対する板厚ｔ１の比率（ｔ１／ｔ２）が０．４０以上０．７７以下に設定され、フランジの幅方向中央部と両縁端部の板厚差により生じる段差をフランジ内面側に有しているので、鋼材量の増加を招かずに、応力集中による接合部近傍の梁フランジの早期の破壊を回避することができる。【選択図】図１
