本文研究了细长板的弯剪相互作用。在大弯矩和大剪力范围内，对纵、横加劲梁进行了6次大型试验。在纵向上，腹板加劲采用梯形加劲肋，其中两根位于腹板中部深度，另外四根位于受压区。从整体性能和腹板屈曲角度详细介绍了试验过程和试验结果。这些大梁被分成三组；在每一组中，其中一个参数是不同的。在通用代码ABAQUS中建立了数值模型，并与试验结果进行了验证，包括初始刚度、阻力和破坏模式。最后对en1993 -1-5规定的最大荷载和设计阻力进行了比较和讨论。采用有效宽度法和减小应力法计算设计阻力。
In this paper the bending-shear interaction of slender plates is studied. Six large tests were performed on longitudinally and transversally stiffened girders in the range of high bending moment and shear force. In longitudinal direction the web was stiffened with a trapezoidal stiffener positioned at the mid web depth for two girders and in the compression zone for the other four girders. The test procedure and test results are presented in details from the point of global behaviour and web buckling. The girders were divided in three groups; within each group one of the parameters was varied. Furthermore, a numerical model built in the general-purpose code ABAQUS is presented and verified against test results regarding initial stiffness, resistance and failure mode. In the last part of this paper the maximum load and the design resistance according to EN 1993-1-5 are compared and discussed. The design resistance was calculated with both options, according to the effective width method and the reduced stress method.
