lever spike extractor

With the restraint of flange to web considered, the buckling stress of steel beam web under different stress is analyzed. The condition for instating web stiffener is given.

考虑翼缘对腹板的约束作用分析处于不同状态下钢梁腹板的临界应力，得出腹板加劲肋的设置条件激励与约束的关系；

Investigation into Elasto-Plastic Buckling Strength of Web with Longitudinal Stiffener in I-Section Girder

纵向加劲肋对钢梁腹板弹塑性屈曲承载能力影响的研究

Study of limite ratio of height to thickness of web when stiffener is not set up on steel beam

不设加劲肋的钢梁腹板高厚比限值研究

The load-bearing condition of the steel double box girder bridge in a variety of situations was really simulated. The major parameters including the thickness of web, the stiffener density and the diaphragm density are studied.

主要研究了腹板厚度、顶、底板和腹板加劲肋间距、横隔板间距、横梁间距等结构参数对双箱钢梁承载能力和应力分布的影响。
