| 中文摘要: |
| 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武，给出极限荷载的计算公武与数值结果，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，说明结果是合理的． |
| 英文摘要: |
| Using Mises yield condition, limit loads of the simply sup ported annular plate on inner boundry under linear distribution load are analyse d by method of weighted residuals in this paper. The formular and corresponding numerical results of the limit loads have been given for two various types of l inear loads. And the influence curves of limit loads are also illustrated. Com pared with results based on maximum moment limit condition shows that the result s is more reasonable. |
