STEEL BEAM REINFORCING METHOD AND STEEL BEAM
To provide a steel beam reinforcing method and a steel beam capable of accurately preventing the early occurrence of cracks from the rear end (shape discontinuity) of the widened portion in the beam-column joint structure of a steel column and a steel beam, when partially widening, such as by joining a rectangular steel plate to the flange side of the steel beam near the joint with the steel column.SOLUTION: A steel beam reinforcing method in which a steel beam where the flange is partially widened at the joint with the steel column, a reinforcing member having a length less than 2.0 times the flange width is joined to the surface of the flange, including a flange longitudinal position where a rear end of a portion where the flange is partially widened is located.SELECTED DRAWING: Figure 1
【課題】鉄骨柱と鉄骨梁の柱梁接合構造において、鉄骨柱との接合部近傍で鉄骨梁のフランジ側面に矩形の鋼製プレートを接合するなどして部分的に拡幅する際に、拡幅部の後端（形状不連続部）からの亀裂の早期発生を的確に防止することができる鉄骨梁の補強方法および鉄骨梁を提供する。【解決手段】鉄骨柱との接合部でフランジが部分的に拡幅された鉄骨梁において、前記フランジの表面に、前記フランジが部分的に拡幅された部分の後端が位置するフランジ長手方向位置を含めて、フランジ幅の２．０倍未満の長さを有する補強部材を接合することを特徴とする鉄骨梁の補強方法。【選択図】図１
