In Australia, all structures—without exception—must be designed to withstand internal wind pressure, which makes up a significant portion of the combined wind loads on a building. For the optimal structural design of all building types, it is essential for architects, designers and specifiers to understand the recent changes to AS/NZS 1170.2, which sets out the procedures for calculating wind speeds and resulting wind actions on buildings.

Calculating internal wind design pressures for steel framed walls & ceilings: Key changes to AS/NZ 1170.2:2021 is an essential guide to the recently updated AS/NZS 1170.2 and how it impacts the calculation of internal design pressures for steel-framed walls and ceilings. We outline the process for determining internal design pressures and highlight some of the important new requirements in AS/NZS 1170.2 that will impact the basic methodology, including changes to wind regions and terrain categories, the introduction of a climate change factor, and how to calculate internal pressure coefficient for buildings with dominant wall openings.
