摘　　要：文章对目前国内油罐顶盖市场上常用的凯威特加联方网格形式和双向子午线网格形式钢网壳的整体稳定性,利用ANSYS软件进行了详细计算,并对两种形式网壳性能进行了对比,结果是在满足同样整体稳定安全系数的前提下:凯威特加联方网格形式的网壳整体刚度大,用钢量小;对于双向子午线网格形式的网壳,采用H型钢可以减少用钢量。This paper calculates the stability of Kiewitt grid shell and two-way meridian grid shell,which are commonly used for large-scale oil tank top,based on ANSYS software,and compares their performance.The results show that based on the same stability safety factor,Kiewitt grid shell has high rigidity and low steel consumption,while two-way meridian grid shell has less consumption of H type steel.
