摘要

研究了梯形加劲纵向加劲工字梁的抗剪性能。它首先报告了在亚琛工业大学进行的4次全尺寸测试，对带有强封闭加强筋的加劲板进行了测试。正如预期的那样，子面板的故障一直在控制。然后描述了一个专门的FEA壳模型，并根据这些结果和其他实验来源进行了验证。用数值工具进行的参数化研究有助于指出欧洲规范3第1.5部分关于加筋板在弯曲和剪切方面可以改进的几个方面。

EXPERIMENTAL AND NUMERICAL INVESTIGATIONS FOR I-GIRDERS IN BENDING AND SHEAR STIFFENED BY TRAPEZOIDAL STIFFENERS

The paper investigates the shear resistance of I-girders longitudinally stiffened by trapezoidal stiffeners. It first reports on 4 full-scale tests performed at RWTH Aachen, on stiffened panels with strong closed stiffeners. As expected, failure in the subpanels has been governing. A devoted FEA shell model is then described and validated towards these results and other experimental sources. Parametric studies led with the numerical tool help pointing out several aspects where the Eurocode 3 Part 1.5 recommendations on stiffened panels in bending and shear may be improved.
