国外空间钢结构设计与实践——以体育场馆罩棚结构的找形技术为例

Design and Practice of Overseas Spatial Steel Structures:Taking the Form-Finding Technology of Stadium Canopy Structures as an Example

针对国外空间钢结构的设计与实践,以体育场馆罩棚结构为研究对象,对相关的找形技术进行了综述。首先回顾了近20年重大赛事体育场馆的发展,介绍了体育场罩棚的结构体系。为了解找形技术的发展概况和瓶颈,从基本原理、发展趋势和现有工具三方面对基于物理实验和数值模型的找形方法进行了讨论,并根据1048篇英文文献和会议论文,对近10年相关研究的发表时间和关键词进行了统计分析,明确了AI技术融合、结构找形等问题。最后,结合找形技术在体育场罩棚结构中的应用案例,梳理了相关技术的不足之处和未来的研究展望。

Focusing on the design and practice of overseas spatial steel structures,this paper presented a review of the relevant form-finding technologies with stadium canopy structures as the research object.It begined by reviewing the development of stadiums for major events over the past two decades and introduces the structural systems of stadium canopies.To understand the development overview and bottlenecks of form-finding technologies,discussions were conducted on form-finding methods based on physical experiments and numerical models from three aspects:basic principles,development trends,and existing tools.A statistical analysis was also performed on the publication dates and keywords of 1048 English journal articles and conference papers from the last decade,highlighting issues such as the integration of AI technology and structural form-finding.Finally,by examining application cases of form-finding technology in stadium canopy structures,the shortcomings of related technologies and future research prospects were identified and discussed.
