摘要
通过对 10 0 0 0m3天然气和 32 0 0m3液化石油气球罐不同支柱型式及其与球罐连接结构进行了研究 ,分别对操作工况和地震工况的应力进行了有限元分析 ,得出了一些结论 。
The types of spherical tank column and connection structure between column and shell including a 10000 m 3 natural-gas spherical tank and a 3200 m 3 liquefied-petroleum-gas spherical tank were studied.The stress under operating condition and earthquake condition was analyzed by means of the 3-dimensional finite element of ANSYS structure analysis software. Some conclusion was gotten and it is valuable and good reference for selecting types of spherical tank and connection structure between column and shell.
