摘要
本文采用Hsich-Ting-Chen强度准则,对轴对称条件下混凝土板冲切强度进行了分析,推导出破坏时的冲切面上正应力和剪应力表达式;采用刚塑性模型,给出了轴对称破坏机构,再利用虚功原理求得破坏荷载的上限。计算公式形式简单,计算结果与已有结果相比符合较好。
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.
