本文采用全非线性数值分析方法，参数化地考察了几何板和加劲筋性能以及初始缺陷对受剪切荷载作用的梁腹板横向加劲筋性能的影响。特别注意了各种几何参数对加劲板挠度和加劲板峰值承载力的影响。还考虑了材料屈服应力的变化。结果表明，在各种几何形状中，面板容量随加劲板尺寸的变化而变化，并得出结论，加劲板的抗弯刚度是主要的设计考虑因素。配套的论文根据当前可用的设计模型来研究结果，并开发了一个简单的模型，该模型准确地再现了研究结果。(A)另见ird摘要829060号。
This paper uses fully non-linear numerical analysis to examine parametrically the effect of geometrical panel and stiffener properties and initial imperfections on the behaviour of transverse stiffeners in girder web plates subject to shear loading. Particular attention is paid to the way in which the various geometrical parameters affect the deflexion of the stiffener and the peak capacity of the stiffened plate. Variation in material yield stress is also considered. The results demonstrate the way in which panel capacity varies with stiffener size for a full range of geometries, and concludes that stiffener bending rigidity is the major design consideration. The companion paper looks at the results in terms of currently available design models, and it develops a simple model which accurately reproduces the results of the study.(A) See also IRRD abstract No 829060.
