Abstract:Tianjin Haihe Education Park Sports Center Stadium is a 29,000seat mediumsized stadium with roof canopy around the stadium body. The steel pipe truss structure was adopted in the roof. Every piece of the main truss is an innercantilever truss with the biggest cantilever span of 40m. The main truss adopts different support forms according to the lower column grid arrangement. The structural layout of the roof was introduced comprehensively. An overall analysis was carried out on the roof structure by using SAP2000 software. The calculation and analysis of the singlepiece trusses were supplemented. The finite element analyses were carried out on support joints and typical joints  by using ANSYS software, and the calculation results can meet the requirements of the relevant codes.

Keywords:steel pipe truss structure; wind tunnel test; tubular joint
