REINFORCEMENT STRUCTURE OF STEEL PERFORATED BEAM
To ensure the yield strength of a steel beam by preventing the web having a rectangular through-hole from buckling, etc.SOLUTION: The reinforcement structure of a steel perforated beam includes: a web 12 provided with a rectangular through-hole 20; a steel beam 10 that has an upper flange 14 located at the upper side of the web 12 and a lower flange 16 located at the lower side of the web 12; an upper reinforcement plate 30U joined to the web 12 and the upper flange 14 at the upper side of the through-hole 20; a lower reinforcement plate 30 L joined to the web 12 and the lower flange 16 at the lower side of the through-hole 20; and a pair of vertical stiffeners 50 each of which extends vertically along vertical sides 20B of the rectangular through-hole 20 located at the left and right sides of the through-hole 20.SELECTED DRAWING: Figure 1
【課題】矩形状の貫通孔が形成されたウェブの座屈等を抑制し、鉄骨梁の耐力を確保することを目的とする。【解決手段】鉄骨有孔梁の補強構造は、矩形状の貫通孔２０が形成されたウェブ１２と、ウェブ１２の上側の上フランジ１４と、ウェブ１２の下側の下フランジ１６と、を有する鉄骨梁１０と、貫通孔２０の上側で、ウェブ１２と上フランジ１４とに接合された上補強プレート３０Ｕと、貫通孔２０の下側で、ウェブ１２と下フランジ１６とに接合された下補強プレート３０Ｌと、貫通孔２０の左右両側で、矩形状の貫通孔２０の縦辺２０Ｂに沿って上下方向に延びている一対の縦スチフナ５０と、を備える。【選択図】図１
