摘　　要：研究论述了某乐园建筑的大跨度屋面钢结构在设计中遇到的难点及解决办法,对此屋面钢结构,根据建筑要求选取合适的结构形式;分析不同支座优缺点以及选用合适的支座类型,进行拉索单元分析、施工阶段分析等。选取了一个复杂的支座节点进行有限元分析,并且对如何设置节点板提出合理建议。This study discusses the difficulties and solutions encountered in the design of a largespan roof steel structure of a park building.For this roof steel structure,the structural designer selects the appropriate structural form according to the requirements of the building,analyze the advantages and disadvantages of different supports and select appropriate support types,conduct cable unit analysis,construction phase analysis,etc.A complex support node was selected for finite element analysis,and reasonable suggestions were made on how to set up the node plate.

关 键 词：三角桁架 固定铰支座 弹性支座 只拉单元 施工阶段分析 有限元节点分析
