| 摘 要： | 剪切中心的研究与截面上剪应力分布规律有关。等宽度的槽型截面也不例外。本文通过不同的假定介绍按材料力学、薄壁开口截面理论推导出的剪切中心位置计算表达式并给出示例作对比说明。最后提出对厚壁槽型截面的修正公式。

| Abstract: | The location of shear center on standard channel section is seen to be a function of cross section and is closely related with the characteristic of shear stress distribution.In this paper,utilizing various assumptions,expressions to determine the position of shear center of channel section are derived based upon strength of meterials and thin_walled beam theory.A numerical example has been worked out for illustration and comparison only.However,in the case of thickened flanges,a revised formula is developed for shear center.Conclusions are drawn and further study is required. |
