This national sports stadium is designed to serve both as a lasting public legacy and a venue for the 2023 World Athletics Championships. It features a permanent 15,000-seat stadium that can be expanded to 40,000 seats for tournaments. The stadium's roof, a key component of its dual-purpose design, is supported by a prestressed, bicycle wheel cable system. This structure allows the roof to withstand various loads while maintaining structural efficiency. The project team effectively employed computational design processes to optimise the structural design.
An efficient and elegant cable-net stadium roof solution. The prestressed, bicycle wheel cable system minimised structural depth and provided a unique architectural solution while ensuring the roof's stability and efficiency.
The use of computational design processes enabled quick assessment and iteration of design solutions, facilitating effective communication and decision-making among stakeholders and helped to optimise materials, geometry, and construction methods.
Precise and stringent tolerance controls and precision manufacturing techniques ensured that the complex structural components were assembled accurately, reducing on-site adjustments and enhancing constructability.
Close collaboration between structural engineers, architects, and contractors led to a design that met both aesthetic and structural requirements, ensuring the project's overall success and stakeholder satisfaction.
