Wind is one of the dominant loads acting on Australian buildings. Designing for it correctly keeps roofs on, walls standing, and occupants safe — and it's governed by the Australian Standard AS 1170.2.
Australia's wind regions
Australia is divided into wind regions, from the relatively sheltered Region A across most inland and southern areas, to the cyclonic Regions C and D along the northern coast. Your site's region sets the baseline wind speeds your structure must resist.
What affects the wind load on your building
- Regional wind speed and the importance of the structure
- Terrain category — open ground versus built-up suburbs
- Topography — hills and escarpments accelerate wind
- Building height, shape and the size of openings
Why it matters
Under-designing wind connections is a common cause of roof and cladding failure in storms. Our structural team analyses wind loads and designs the bracing, tie-downs and connections needed for your site, from single-storey homes to high-rise and exposed coastal projects.
