Halo Fabric Roof, Optus Stadium

Halo Fabric Roof, Optus Stadium

Project Details

Location: Optus Stadium, Perth WA

Completion Date: 2017

Size: 35,000 sqm

Fabric: PTFE - Chukoh FGT800, Sefar Tenara 4T40HF

The crowning cap of the Optus Stadium is the “halo” roof that appears to float above the main seating bowl and façade. The use of architectural membrane materials create an ultra-lightweight roof, enabling a lightweight steel frame to be constructed that compliments the minimal form of the roof.

The Brief

The key design brief from the client, was for the stadium and it’s ‘Halo’ roof to be designed in keeping with Perth’s sub-tropical climate, as well as being easy to construct and install. The architectural concept for the stadium was to create a unique design, recognisable as a Western Australia landmark across Australia and the world. The ‘Halo’ membrane roof designed as a keynote feature of the project.

The Concept

The architectural intent for the roof was to create an illusion of a light, open floating ‘halo’. This concept was the inspiration for MakMax Taiyo Middle East’s choice of materials used, as well as the engineered form and final detailing.

The roof was designated as one of the key stadium features by the project architectural team and an extremely strong focus was maintained throughout the project on design detailing and finishes.

The Materials

The Optus Stadium roof structure is a continuous fabric roof, free from movement joints and integrated with lighting, PA and other systems. The translucent roof was enhanced by the use of 2 fabrics – a strong, heavy-duty PTFE, combined with a 40% translucency ePTFE fabric – with the contrasting light transmissions creating a visually exciting texture to the ‘halo’.

The roof support structure consists of fifty 35m triangular truss cantilevers. The bottom chords of the trusses aren’t triangulated by bracing but rely on Vierendeel design action. This Vierendeel action is significant for the design of the ‘halo’ roof robustness, protecting the structure from out-of-balance plane loads in the event of a loss of a panel of fabric.

The Result

The design was made possible through MakMax’s strong design and installation collaboration with the whole project team including architects, project engineers, steel fabricators.
