STEEL BEAM, COLUMN-BEAM JOINT STRUCTURE AND STRUCTURE PROVIDED THEREWITH
To provide a steel beam, a column-beam joint structure and a structure provided therewith in a simple structure capable of improving plastic deformation capacity at an end part in a material axis direction upon short load action such as earthquake force.SOLUTION: A steel beam 1 has an upper flange 11, a lower flange 12, and a web 13 jointing the upper flange and the lower flange, which is provided with: main stiffeners 14 jointing a space between the upper flange and the lower flange at a predetermined position in its material axial direction; and through hole 13h formed in the web to overlap the main stiffeners in a beam width direction.SELECTED DRAWING: Figure 2
【課題】単純な構造により、地震力等の短期荷重作用時に材軸方向の端部の塑性変形能力を改善することのできる鉄骨梁、柱梁接合構造およびこれを有する構造物を提供する。【解決手段】上フランジ１１と、下フランジ１２と、上フランジと下フランジとを連結するウェブ１３とを有する鉄骨梁１の材軸方向の所定位置において、上フランジと下フランジの間を連結する主スチフナ１４が設けられるとともに、ウェブには主スチフナと梁幅方向に重なるように貫通孔１３ｈが形成されている。【選択図】図２
