STIFFENING STRUCTURE AND H-SHAPED CROSS SECTION MEMBER HAVING STIFFENING STRUCTURE
To provide a stiffening structure and an H-shaped cross section member having the stiffening structure capable of simultaneously realizing reduction in shearing stress of a web, suppression of local buckling and clip ring, and improvement in torsional resistance performance.SOLUTION: A stiffening structure 10 for an H-shaped cross section member 100 having a web 1 and two flanges 2, comprises: a first stiffening member 11 provided on one side of the web 1 and configured to form a longitudinal space 21 between itself and the web 1; and a second stiffening member 12 provided on the other side of the web 1 and configured to form a longitudinal space 22 between itself and the web 1. An extending direction of the first stiffening member 11 has a positive inclination angle with respect to a plane including the flange 2, with a counterclockwise direction as a positive direction. An extending direction of the second stiffening member 12 has a negative inclination angle with respect to the plane including the flange 2, with the counterclockwise direction as the positive direction. The first stiffening member 11 and the second stiffening member 12 are arranged so as to cross the web 1 in a plan view.SELECTED DRAWING: Figure 1
【課題】ウェブのせん断応力の低減と、局部座屈及びクリップリングの抑止と、耐ねじれ性能の向上とを同時に実現可能な補剛構造及び補剛構造を有するＨ形断面部材を提供する。【解決手段】ウェブ１と２つのフランジ２とを有するＨ形断面部材１００用の補剛構造１０が、ウェブ１の一方の面に設けられ且つウェブ１との間で長手空間２１を形成するように構成された第１補剛部材１１と、ウェブ１の他方の面に設けられ且つウェブ１との間で長手空間２２を形成するように構成された第２補剛部材１２と、を具備し、第１補剛部材１１の延在方向が、フランジ２を含む平面に対して、反時計回りを正方向として、正の傾角を有しており、第２補剛部材１２の延在方向が、フランジ２を含む平面に対して、反時計回りを正方向として、負の傾角を有しており、第１補剛部材１１と第２補剛部材１２とが、ウェブ１に対して、平面視において交差するように配置されている。【選択図】図１
