ANALYSIS METHOD, DESIGN METHOD, MANUFACTURING METHOD, AND PROGRAM
To provide an analysis method capable of highly accurately analyzing a beam to which a vertically equally distributed load acts in a state where both end portions are rigidly bonded or semi-rigidly bonded to a support member and is not restrained by warpage regardless of a large beam and a small beam.SOLUTION: An analysis method evaluates lateral buckling resistance of a steel beam when a vertical distribution load is applied from a floor slab 40 to a steel beam 10 whose both ends 10a are supported by a support member 20. The steel beam is an object for which a shape steel is used in which an upper flange 11 and a lower flange 12 are connected by a web 13. At least one of both ends of the steel beam in a material axial direction Z is rigidly or semi-rigidly bonded to the support member. In an intermediate portion 10b in a material axial direction of the steel beam, lateral movement of the upper flange in a width direction X is restricted, and intermediate load which is an equal distribution load is applied to an upper flange from an upper portion. Under conditions where an end load is applied to both end portions in the material axial direction of the steel beam, the lateral buckling resistance of the steel beam is calculated from a formula.SELECTED DRAWING: Figure 4
【課題】両端部が支持部材に剛接合又は半剛接合され反り拘束されていない状態で鉛直等分布荷重が作用する梁を、大梁及び小梁に関係なく高い精度で分析できる分析方法を提供する。【解決手段】両端部１０ａが支持部材２０に支持された鉄骨梁１０に床スラブ４０から鉛直等分布荷重が作用する場合の鉄骨梁の横座屈耐力を評価するための分析方法であって、上フランジ１１と下フランジ１２とがウェブ１３で連結された形鋼が用いられる鉄骨梁を対象とし、鉄骨梁の材軸方向Ｚの両端部のうち、少なくとも一方の端部が支持部材に剛接合又は半剛接合されるとともに、鉄骨梁の材軸方向の中間部１０ｂにおいて、上フランジの幅方向Ｘの横移動が拘束されて、且つ上フランジに上方から等分布荷重である中間荷重が作用し、且つ鉄骨梁の材軸方向の両端部に端荷重が作用する条件下で、鉄骨梁の横座屈耐力を、数式から算出する。【選択図】図４
