[提要]  在规范GB50010-2002基本规定的基础上，展开板柱节点受冲切承载力计算方法的讨论。提出的计算公式是对规范公式的补充，特别是对于非主轴坐标下不平衡弯矩在临界截面上产生的最大剪应力的计算方法，可应用到任意多边形的临界截面中。该法力学概念明确、适用范围广，其计算结果与试验值吻合较好。

A calculating method for punching shear strength of slab-column connection transferring shear and unbalanced bending moment, which satisfies the requirement of the GB50010-2002 code, is presented in detail. Especially, the formulae to calculate the nominal maximum shear stress of rectangle or non-rectangle critical sections with non-principle axes are the supplements of code. The method is clear in mechanical concept and has wide application range. The calculated results agree well with the tested results.
Keywords:  punching shear strength; critical section; nominal shear stress method; concrete slab; slab-column connection; unbalanced bending moment
