在局部均布荷载和线性分布荷载共同作用下环板的塑性极限分析

The Plastic Limit Analysis of Annular Plates Under Local Uniform and Linear Load

在文献[1]的基础上，进一步将广义阶梯函数应用于环板在复杂荷载作用下的塑性极限分析问题。针对固支和简支环板，并考虑局部均布和线性分布荷载共同作用的3种可能分布形式，应用广义阶梯函数法给出了环板的极限荷载的计算公式。

In this paper, on the basis of the reference[1],further, the generalized step function is applied to the plastic limit analysis of annular plates under complicated loads. It aims to clampd and simply supported annular plates at outside boundary supporting. The three possible distribution form on local uniform and linear load have been considered. The calculating formulas of limit load of annular plates have been given out by generalized step function.
