摘要

摘要: 波浪腹板工形梁的局部承压性能目前国内外研究较少。在总结前人对平腹板和梯形波折腹板梁局部承压极限承载力研究工作的基础上,对波浪腹板工形梁的局部承压性能及设计方法进行研究。通过有限元数值分析,揭示波浪腹板工形梁在局部压力作用下的破坏形式以及腹板几何初始缺陷对局部承压性能的影响,在几何参数分析的基础上建立局部承压极限承载力的简化计算公式。最后针对同时承受局部荷载和弯矩的波浪腹板工形梁,建立截面弯矩与局部压力之间的M-P承载力相关计算公式,并通过有限元数值计算进行验证。

Abstract: The strength of sinusoidal web I-shaped girders under patch loading is not studied well up to now. It wassummarized the previous research work on plane web girders and trapezoidal corrugated web girders, and thenpresented a systemic study on the patch loading behavior of I-shaped girders with sinusoidal corrugated webs. Failuremodes and the influence of initial geometrical imperfection of web were investigated by nonlinear shell elementanalysis. Based upon parametric studies on sinusoidal corrugated web girders, a simplified design formula forestimating the ultimate strength of the girders under patch loading was proposed. In the case of I-shaped girder oftensubjected to combined patch loading and bending moment, an interaction design formula for predicting its limitstrength was proposed accordingly, and validated by FE numerical results.
