Design of large-span steel structure for the National Stadium, Beijing

摘要

The structural form of the Beijing National Stadium (The 'Bird's Nest') is unusual and iconic. This paper describes the rational behind its framing solution, the types of analysis adopted and the loading conditions considered, Given its complex geometric form, issues of fabrication and buildability were especially difficult and are described. Theoretical design of the more complex joints was verified by FEA and back up model load testing. An explanation is given of the construction technique.
