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。
The study of shear center is related to the distribution of shear stress on the section. Equal width groove section is no exception. In this paper, the expression of shear center position derived from the theory of material mechanics and thin-walled open section is introduced through different assumptions and examples are given for comparison. Finally, the correction formula of thick-walled groove section is proposed.
