本文采用Hsich-Ting-Chen强度准则对混凝土板的轴对称极限冲切强度进行了分析。推导了冲裁破坏面上的应力表达式。利用刚塑性模型建立了轴对称破坏机理，并通过虚功方程得到了极限冲切强度的上界。数值结果与其他可用数据非常一致。
In this paper, the analysis on axisymmetrical ultimate punching strength of concrete slabs is presented by using Hsich-Ting-Chen strength criterion. The expressions for the stresses on punching failure plane have been derived. By use of the rigid-plastic model, the axisymmetrical failure mechanism is established, and the upper bound of ultimate punching strength is obtained by the virtual work equation. The numerical results are in good agreement with other available data.
