| 摘 要： | 单层网壳结构已被应用于大型储液罐的顶盖结构中,而目前在此类顶盖的分析设计中,往往忽略下部罐体与上部网壳顶盖间的协同工作性能。考虑到下部罐体,利用通用有限元程序模拟上下部的径向连接刚度,分析网壳顶盖的整体稳定性能;并基于附加质量法,建立储液罐抗震简化分析的附加质量模型,研究下部罐体、径向连接刚度等因素对网壳顶盖动力性能的影响。结果表明,上下部协同工作性能对网壳顶盖的稳定性、动力性能影响较大,在结构分析设计中,应综合考虑。

| Abstract: | The single layer latticed shell has been adopted in the roof of large storage tank, but the coordinated working between roof and tank is ignored in the design and analysis of latticed shell roof. The radial connection stiffness between upper roof and tank was simulated by the general finite software in this paper, and the global stability of roof was analyzed, which considered tank; Then the simplified analysis model was established on the basis of added mass method, the influence of tank and radial connection stiffness on dynamic performance of roof was analyzed. The results show that the coordinated working has a great impact on the stability and dynamic performance of latticed shell roof, which should be considered comprehensively in the structural analysis and design. |
