Chengdu Phoenix Mountain Sports Center consists of a professional football stadium able to accommodate 60,000 spectators. It also includes a sports arena with a capacity of 18,000 spectators and a club connecting the sports arena with the football stadium. The football stadium has a one-storey basement and six floors, with a roof height of approximately 64m.
This project demonstrates development in design and construction methods for large cable supported domes with central openings. The design team carefully considered the flow of forces around the asymmetric roof, using an inner ring steel truss and prestressed sunflower configuration cable layout to create an efficient structural form.
This is innovative engineering design making fantastic use of scale model testing and Ethylene tetrafluoroethylene (ETFE) testing to verify findings and ensure successful completion of the project.
