大开孔补强设计探讨

Strengthening Design of Large Opening

从大开孔设计方法研究、应力测试分析和标准分析入手,根据开孔边缘的应力分布特点,提出了大开孔适宜的补强结构形式,并对大开孔采用补强圈结构进行了探讨。

From view points of design method of large opening,stress measurement and analysis,as well as code analysis, based on the feature of stressing along the edge of opening,a suitable structure form for strengthening design of larger opening is put forward. The circle structure of strengthening is also discussed.
