Please describe the project specifications
The stadium is an iconic building representing the amazing quality that Qatar is ensuring for 2022 FIFA world cup. The boldly futuristic shape of the 40,000 capacity arena mirrors the innovative, ambitious spirit of Qatar. The roof structure consists of 4 main arches of 180m length confined by an outer ring truss. The unique retractable roof provides shading to spectators before matches while enabling a proper bowl precooling.
Pfeifer structures worked on the retractable membrane manufacture, this membrane roof is required to close in approximately 30 minutes using a number of tension belt systems. The roof will provide shade to the entire pitch and contribute to the efficiency of the stadium’s innovative cooling system.
What is unique or complex about the project?
The whole canopy is divided into two panels. The surface area of one panel is around 5000sqm, it greatly increase handling difficulty. Since the retractable roof require membrane-belt-system stitched onto the main membrane. The detail processing is quite complicated and during main membrane welding the belt need be held under high pre-tension.
The project has been installed and finished and was put into use. The retractable membrane structure creates a high-volume cooling space.
