环板在两种不同荷载共同作用下的塑性极限分析

THE PLASTIC LIMIT ANALYSIS OF ANNULAR PLATES UNDER THE MUTUAL ACTION OF TWO DIFFERENT LOADS

本文针对外边界支承环板的塑性极限分析问题,应用奇异函数给出一种简便的分析方法,并分四种情况给出环板在两种不同荷载共同作用下的极限荷载的计算公式。

In this paper,by the application of the singular function,a simple method is given for the plastic limit analysis of annular plates with the outer boundarysupported.In the solution,the four cases of the loading conditions when theplate is subjected to the mutual action by two diffdrent loads have been consider-ed and the formulas for the calculations of the limit loads of the annular platesunder the two different loads have been given.
