［摘要］兰州水舞秀场馆分为舞台区和看台区，结构形式分别为网架与桁架的组合结构及大跨网架结构，具有大跨度、主体结构开大洞、环境温差大、屋顶主结构变形要求严格及屋顶主结构与幕墙连接复杂等设计难点。详细介绍了钢结构的节点设计、钢结构与幕墙的连接设计、主体钢结构的结构体系及特点。采用MIDAS软件对结构进行了温度分析、基本静力和动力特性分析。分析结果表明，该场馆结构布置合理，结构整体刚度较大且分布均匀。

Abstract:Lanzhou Water Dance Show Venue is divided into stage area and audience area. The structural forms include the large-span  grid and a composite structure of grid and truss. The project has many design difficulties, such as large span, large opening in the main structure, large environmental temperature difference, strict deformation requirement of roof main structure and complex connection between roof main structure and curtain wall. The joint design of steel structure, the connection design of steel structure and curtain wall, and the structure system and characteristics of main steel structure were introduced. Software MIDAS was used for temperature analysis, basic static and dynamic characteristics analysis of the structure. The analysis results show that the venue structure layout is reasonable and the overall structure stiffness is strong and evenly distributed.

Keywords:Lanzhou Water Dance Show Venue; composite structure of grid and truss; irregular opening; temperature effect; joint design
