摘　　要：山东省聊城摩天轮采用刚柔混合支承形式一上部轮盘由140根柔性钢拉索和7根刚性桁架式支撑梁交替均布构成,轮盘由下部4根柔性主拉索和2根刚性主立柱支撑,该支承形式传力路径简洁合理、结构形式安全可靠。本文通过有限元方法对该摩天轮进行了结构极限强度分析、正常使用极限状态分析、偏栽分析、抗震分析、安装过程分析、轮辐索失效分析、局部精细有限元分析。由计算结果可知,极限风荷载是摩天轮设计的控制性荷载。该分析结果和方法可供类似结构研究设计参考。The supporting form of Liaocheng Ferris Wheel is a combination of rigid and flexible--the wheel is consists of 140 flexible cables and 7 rigid truss beams. The wheel is supported by 4 main flexible cables and 2 main rigid columns. This supporting form is safe and reliable with a concise and reasonable load path. The ultimate strength analysis, serviceability limit state analysis, offset load condition analysis, seismic analysis, installation process analysis, cable failure analysis and local fine FE analysis of the Ferris Wheel were done using FEM in this paper. The result of analytical study indicates that ultimate wind load is the control load in the design of Ferris Wheel. Besides, the analysis result and method might provide references for similar research.
