Abstract:As a professional football field without tracks, the Shanghai Pudong Stadium has a rectangular shape with a dimension of 211 m×173.4 m. A special spoke wheel structure system with an internal compression ring and a tension ring underneath was adopted. High correlation between structural configurations and internal force for such a novel cable-ring structure is a great challenge for the construction of the steel structure roof. Combined with the actual characteristics of the project, the construction process and construction analysis are carried out. The steel members are further designed and then processed. And the key technologies of vertical control support construction, roof steel structure installation and cable tension construction are introduced in detail. This paper summarizes the innovative construction technology successfully used in the implementation of steel structure roof of Pudong Football Stadium.
