BIM技术在大型超大跨度钢结构拱桁架屋盖施工中的应用——以2022年杭州亚运会曲棍球场为例

Application of BIM Technology in the Construction of Large and Super-long Span Steel Structure Arch Truss Roof——Taking the 2022 Hangzhou Asian Games Hockey Stadium as an Example

钢结构以其强度高、质量轻、结构形式灵活等诸多优势,已广泛应用于建筑工程中,尤其是大跨度结构建筑;但也存在施工深化设计难度大、机械化作业施工精度控制要求高等问题,加大了施工难度。为此,文章以2022年杭州亚运会曲棍球场超大跨度钢结构屋盖为例,展开了钢结构BIM三维深化、方案仿真模拟、有限元分析等技术应用研究,为解决项目超大跨度异形空间钢拱桁架屋盖的深化与施工技术难题,以及解决类似超大跨度钢拱桁架屋盖结构施工难题提供了参考。

Steel structures have been widely used in construction engineering, especially for large-span structural buildings due to their high strength, light weight, flexible structural forms, etc. However, there are also problems such as the difficulty of deepening the design of construction and high requirements for mechanized operation and construction precision control, which increase the difficulty of construction. Therefore, this paper takes the super-long span steel structure roof of the Hockey Stadium of the 2022Hangzhou Asian Games as an example to carry out the technical application research on BIM 3D deepening of steel structures, scheme simulation and finite element analysis,which provides references for solving the technical problems of deepening and construction of the super-long span special-shaped space steel arch truss roof of the project as well as solving the construction problems of similar super-long span steel arch truss roof structure.
