OPENING PART REINFORCING STRUCTURE OF STEEL BEAM
To effectively suppress stress concentration around a corner part of a polygonal or substantially polygonal shape opening part formed in a web of a steel beam.SOLUTION: An opening part reinforcing structure 10 comprises: a substantially polygonal shape opening part 60 formed in a web 54 of a steel beam 50; and a plurality of reinforcing plates 70 which are joined to each other on both sides of the web 54 so as to surround the periphery of the opening part 60, and which intersect around a corner 62 of the opening part 60 or which one ends 72A, 72B abutting against the other ends 72A, 72B in a T-shape, when viewed from the front.SELECTED DRAWING: Figure 1
【課題】鉄骨梁のウェブに形成された多角形状又は略多角形状の開口部の角部周囲の応力集中を効果的に抑制する。【解決手段】開口部補強構造１０は、鉄骨梁５０のウェブ５４に形成された略多角形状の開口部６０と、開口部６０の周囲を囲むようにウェブ５４の両面に接合され正面から透視すると開口部６０の角部６２の周囲で交差又は一方の端部７２Ａ、７２Ｂが他方の端部７２Ａ、７２ＢにＴ字状に突当る複数の補強板７０と、を備えている。【選択図】図１
