摘　　要：应用 Mises屈服条件分析内边界简支环板在线性荷载作用下的极限荷载。考虑到 Mises屈服条件的非线性 ,文中应用加权余量法进行分析。针对线性荷载的不同分布形式 ,给出极限荷载的计算公式与数值结果 ,画出极限荷载的影响曲线 ,并与最大弯矩极限条件的数值结果进行了比较 。Using Mises yield condition, limit loads of the simply supported annular plate on inner boundary under linear distribution load are analysed by method of weighted residuals. The formula and corresponding numerical results of the limit loads have been given for two various types of linear loads. And the influence curves of limit loads are also illustrated. Compared with results based on maximum moment limit condition shows that the results is more reasonable.
