按照S H 3046—1992《石油化工立式圆筒形钢制焊接储罐设计规范》,建立了罐壁‐锥板‐蒙皮连接方式的2×104 m3大容量立式网壳顶储罐的空间有限元模型,计算得到了储罐在空罐、半罐、满罐3种工况下的应力分布状态,对储罐进行了强度、破坏和弱顶性能综合评价.根据储罐弱顶性能影响因素的分析计算,提出了使该储罐实现弱顶结构的途径是储罐边缘板厚度由10 m m增大到15 mm或罐顶焊角高度由4 mm减小到3.50 mm.

In accordance with the SH 3046—1992 Petro‐Chemical Design Specification for Ver‐tical Cylindrical Steel Weld Storage Tanks ,to the tank wall‐cone‐plate‐skin connection ,estab‐lishing 2 × 104 m3 vertical lattice roof storage tank spatial finite element model .The stress distri‐bution of empty tank ,half tank and full tank were calculated ,take intensity ,failure and weak roof performance for the comprehensive evaluation .Based on the analysis of influencing factors of the tank weak roof performance ,proposing two ways to achieve the structure of weak roof :the thickness of margin plate increased from 10 mm to 15 mm ,weld bead height of tank deck decrea‐ses from 4 mm to 3 .50 mm .
