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
