针对液压支架结构件一种常用的具有１４个闭室的多层楼式薄壁截面，推导了在剪力和扭矩作用下，计算剪力流的详细过程，为支架强度计算提供较精确的依据，给出了算例及剪力流分布的图示结果。
Aiming at a commonly used multi-storey thin-walled section with 14 closed cells for hydraulic support structure, the detailed process of calculating shear flow under the action of shear force and torque is deduced to provide a more precise basis for the calculation of the support strength , Gives an illustrative example of the shear flow distribution and the results.
