THEORETICAL AND EXPERIMENTAL STUDY ON THE FLEXURAL MEMBER WITH SINUSOIDAL CORRUGATED WEB

摘要: 波浪腹板工形构件由翼缘与波浪腹板通过高频焊接组成,作为受弯构件具有较高的承载效率。基于波浪腹板工形构件截面承载力的简化模型,提出波浪腹板受弯构件强度和抗剪稳定承载力计算公式,同时亦给出考虑波浪腹板剪切变形的构件挠度计算方法;对2根足尺的波浪腹板工形截面梁进行面内加载试验,揭示受弯构件加载破坏过程及破坏机理;同时以有限元分析进行佐证,分析构件初始缺陷对其破坏形式的影响。研究表明,试验结果与有限元分析结果吻合较好,亦验证建议设计方法的合理性。

Abstract: A H-shaped beam with a sinusoidal corrugated web has a high load-carrying efficiency under bending, butit is still verified to be highly efficient as an axial loaded column by a rational design for the section. This paperfocused on the buckling behavior and corresponding design formula of the sinusoidal corrugated web column loadedaxially. Two specimens axially loaded were tested, and the obtained test results were consistent with those of finiteshell element analysis. Additionally, a comparison of load-carrying efficiency and design economics between the flatand corrugated web columns was also made.-
