Wind Regions of Australia

Potential wind speed is just one of many factors taken into account when designing any building, including DomeShelter™ Fabric Structures.

The only thing you, the buyer need be aware of is that the wind region is an important factor and DomeShelter™ consultants will ensure your structure meets the standard required for the region where it is installed

* Terrain Category 2 is open terrain with few trees, surrounding buildings
* Region C - Cyclonic
* Region D - Severe Cyclonic
*Ultimate wind speeds as outlined in Australia New Zealand AS/NZS 1170.2:2011 (R2016) Structural design actions - Wind actions.
*Design Wind Speed is calculated using specific Design Criteria (Terrain Category, Importance Level etc) related your site requirements. An example is: Wind Region Reg B, Importance level 1, Terrain Category 2, Design working life of 25years and maximum average height of 10m = Design Wind Speed 164km/h

Our designers will ask where your Shelter is to be located and take that and more into account when developing a certified engineering solution to ensure the Shelter is built in accordance with AS/NZS 1170.2:2011 (R2016). Safety and integrity is paramount.

wind regions

Regions are marked with the letters A (A1 to A5), B, C and D. Coastal Region boundaries are smooth lines set in from a smoothed coastline by 50, 100 and 200km. Islands 50km from the coast are the same region as the adjacent coast.
