STEEL BEAM REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To suppress a localized buckling of widening sections of a steel beam while enhancing reinforcement effect for the steel beam end parts.SOLUTION: A steel beam reinforcement structure 10 has a pair of flanges 22, 24 opposed to each other in the vertical direction and a web 26 connecting the pair of flanges 22, 24. The steel beam reinforcement structure 10 is provided with a steel beam 20 bonded to a column 12 and reinforcement plates 40 bonded to side ends 22S of the flange 22 and the column 12 to thereby extend a width of the flange 22, and are set to have high strength than the flange 22. The flange 22 and the reinforcement plates 40 satisfy the expression (1).SELECTED DRAWING: Figure 2
【課題】本発明は、鉄骨梁の端部の補強効果を高めつつ、鉄骨梁の拡幅部の局部座屈を抑制することを目的とする。【解決手段】鉄骨梁補強構造１０は、上下方向に互いに対向する一対のフランジ２２，２４と、一対のフランジ２２，２４を接続するウェブ２６と、を有し、柱１２に接合される鉄骨梁２０と、フランジ２２の側端部２２Ｓと柱１２とに接合され、当該フランジ２２の幅を広げるとともに当該フランジ２２よりも高強度とされた補強プレート４０と、を備え、フランジ２２及び補強プレート４０は、式（１）を満たす。【選択図】図２
