The stability of a large opening composites conic shell stiffened with nettings under axial compression, external pressure and their combination is calculated in this paper.
本文用有限元法计算了受轴压、外压、以及轴压和外压联合作用下的大开。

The results show that the toroidal shell is a good type ofcompression ring for large scale storage tanks as well.
实验还表明对于大型拱顶储罐，采用圆环壳型的承压圈有较好的承载能力， 这是一种合理的结构型式。
