摘要
根据材料力学截面最大剪应力公式计算出 H 型钢(按 GB11263-89)的截面惯性矩与面积矩的比值、剪应力系数,为剪应力的精确计算提供方便. 通过对剪应力计算公式的分析,提出了便于工程实用的 H 型钢剪应力计算简化公式,计算精度高,且略偏于安全.
In order to make convenient the precision shear stress calculation, the ratio of cross section second moment to area moment and the shear stress coefficient of H-shape steel (according to GB11263-89 code) are provided based on material mechanics method. On the basis of contrast analysis of shear stress calculation formula, some simplified formulas are put forwarded which are practical with high precision and emphasis on safety.
