| 摘 要： | 石化行业的大型圆筒形储罐罐顶经常采用单层网壳作为支撑结构,根据目前已建工程的资料,此类钢网壳的最大直径已达到60m。由于根据现行规范对网壳的整体稳定计算实现起来比较繁琐,目前国内此类网壳结构在实际工程的设计方法参差不齐。本文将以实际工程为例,提出此类网壳的设计过程和方法,与读者进行探讨。

| Abstract: | Single layer reticulated shell structure is commonly used in petrochemical projects,the diameter of largest reticulated shell is about 60m in practical use.As the design procedure defined in the code for reticulated shell is complicated,by now the actual design method for this type of structure is not the same in different companies.This article is to introduce the engineers a design procedure and method based on an actual project. |
