摘　　要：应用加权余量法求出了承受线性荷载的固支圆板和承受均布荷载的内边界支承环板在 Mises屈服条件下的极限荷载的近似值 ,并与最大弯矩极限条件结果进行了比较 ,说明本文计算结果较合理。On basis of the Mises yield condition and the method of weighted residuals, the limit load approximation solutions of clamped supported circular plate under linear distributed load and annular plate with inner boundary supporting under uniform load are given in this paper. Comparing the present results with those obtained from the maximum moment limit condition shows that the present solutions by using proposed method is reasonable.
