Abstract: Qatar Education City Stadium, one of the main venues for the 2022 Football World Cup in Qatar. This stadium consists of bowl-shaped concrete grandstand, ground floor V-shaped steel columns supporting the upper steel main platform, hub-and-spoke suspension steel roof and façade curtain wall. This paper focuses on the specific application of TS in the deepening design of this project and how to deal with dissimilar structures, assist drafting, and achieve the purpose of improving productivity.
1. Project Overview
The Qatar Education City Stadium (QFS), located in Doha's Education City, Qatar's capital, is one of the venues for the 2022 Soccer World Cup and is designed to accommodate 44,000 people during the tournament. The project's structural form, a bowl-shaped concrete grandstand with a hub-and-spoke suspension steel roof, draws on Islamic architectural features, with the interior and exterior wrapped in translucent triangular panels that change color and pattern according to the sun's orientation and artificial lighting. The stadium uses a year-round cooling system to provide students, faculty, staff, and the local community with access to the stadium and surrounding facilities in Qatar Education City, encouraging generations of Qataris to achieve their fitness goals.
The total steel consumption of the project is about 7,000 tons, 750 tons of tension cables, and the maximum single weight of the members is about 32 tons. The steel roof is a gravity prestressed hub-and-spoke suspension cable diagonally braced primary and secondary beam structure. The structural plane is 250m long axis, 200m short axis, 50m gable height inside the pavilion, and the highest maximum overhanging span is about 61 m. The cable network system consists of outer ring beams, inner ring cables and radial cables between the inner and outer rings. The ring cable space into a saddle type, the plane projection into a ring, V-shaped diagonal braces to support the roof on the cable clamp node. In this project, Wuhan Dunxin is responsible for the deepening design of the main steel structure except the cable structure, and the deepening work is all done in Tekla.
