Technical Bulletin 1009: Wind Actions
Australian Glass Group
Wind loads occur on any structure and must be accounted for during the design process. Critical areas include building corners and edges of roofs. When a wind gust hits a building, it needs to go somewhere. For example; wind hitting a wall of a house will go over the roof and around the sides. Wind hitting the wall will be pushing inwards, this is called positive pressure. Wind going over the roof or around the corner will act to tear off any component of the structure and is called negative pressure. Commonly, negative pressures are stronger than positive pressures only at building corners or the edges of roofs. Currently, there are two standards that address wind calculations in Australia, AS/NZS 1170.2 (Commercial) and AS 4055 (Residential). This document is intended to assist the reader in determining which standard should be used for which occasion, and if loads provided by the client/main contractor/specifier etc. are relevant.
