| 摘 要： | 本文将加权残数法应用于结构的塑性极限分析。针对环形板的不同支承条件,从其承受环形荷载的一般情况出发,分别选择一次、二次、三次多项式为试函数,采用加权残数法的子域法求出了环形板在各种条件下的极限荷载。文中通过例题说明了用加权残数法求极限荷载的方法和过程,并且显示了该方法的简单性及优越性。

| Abstract: | In this paper, the method of weighted residual is applied to the structural plastic limit analysis. By starting from the general case of annular plates bearing the annular load, using the subdomain method in the weighted residual method,choosing simple trial functions (first, second, third-degree polynomial), we have found the solution of the limit load of annular plates on their various supporting conditions. |

| Keywords: | annular plates yield condition trial function residual limit load |
