Wind Tunnel Study Of Facade Pressures Projects In Australia
Overview Of Facade Pressure Study Done For Q1 Tower, Gold Coast
Q1 Tower, located in Surfers Paradise in Queensland, is currently Australia's tallest building at 323m.
A study was carried out to accurately predict the cladding pressures on the building's facade using a risk analysis approach for the effect of internal pressures on net facade pressures. As Surfers Paradise falls within a cyclonic region, both cyclonic and non-cyclonic wind storm scenarios were investigated.
For most areas of the building facade, the wind tunnel estimates were significantly less than the code estimate, particularly along the vertical edges. This is largely attributable to the aerodynamic form of the tower and the rigorous analysis techniques adopted as part of the study.
The study included estimation of the design pressures on the significant canopy structure around the base of the tower, as well as the 33m high roof feature. In addition, the effect of extreme non-cyclonic winds on differential pressures acting across the inter-tenancy walls and floor slabs was also carried out.
Other studies undertaken included a Structural Loads / Building Motion study to determine wind loads on the structural framing of the tower and a Pedestrian Wind Environment Study to ensure wind conditions within and around the development were suitable for the intended uses by patrons and pedestrians.
