摘要
本文运用双矩弱作用屈服条件，分析了密集补强型球壳开孔接管的五类九种破坏机构的完全解，并给出了各类机构所适用的参数范围；从而为建立一种开孔补强设计方法提供了理论基础．本文算例和实验结果符合得很好．
Using the two-moment limit interaction yield condition, five kinds of collapse mechanisms for various geometric parameters of spherical shells with compact reinforcing nozzles are concerned. The completed solutions and the conditions of validity for each mechanism are determined. The results obtained by the presented paper, which are in good agreement with four experimental results, can be used in pressure vessel design.
