STEEL BEAM AND STRUCTURE HAVING THE SAME
To provide a steel beam which is provided with a vertical haunch at a beam end, can mitigate occurrence of stress (strain) concentration, provide through holes for equipment piping at the beam end, and eliminate need for processing through holes for equipment piping at a beam center, and to provide a structure having the same.SOLUTION: In a steel beam having a web and flanges connected to the top and bottom of the web, both end portions of the steel beam in a material axial direction are provided with beam height expansion portions whose beam height is expanded than at the center portion in the material axial direction, and openings are provided in the web of the beam height expansion portions.SELECTED DRAWING: Figure 1
【課題】梁端部に鉛直ハンチが設けられた鉄骨梁において、応力（ひずみ）集中の発生を緩和するとともに、設備配管用の貫通孔を梁端部に備えることができ、梁中央部における設備配管用の貫通孔の加工を不要とすることができる鉄骨梁およびこれを有する構造物を提供する。【解決手段】ウェブと、前記ウェブの上下につながるフランジとを有する鉄骨梁において、前記鉄骨梁の材軸方向の両端部には、前記材軸方向の中央部よりも梁せいが拡大された梁せい拡大部を設け、前記梁せい拡大部の前記ウェブに開口を設ける。【選択図】図１
