Gust Wind Speeds for Design of Structures

This paper defines the peak gust wind speeds specified in applications related to building design and meteorology. The origin of the basic peak gust speed in the Australian Wind Loading Standards since 1971, derived from the Dines anemometer, is discussed, and the response of that anemometer to gusts is compared with the recording system in Automatic Weather Stations (AWS) based on 3-cup anemometers with a 3 s moving average filter that have replaced the Dines since the early 1990s. This later system is shown to significantly attenuate the high frequency wind fluctuations, and hence record lower gust wind speeds than the earlier Dines. A method for comparing gust wind speeds of different durations and for making wind data compatible with AS/NZS 1170.2 and other standards and codes is given.
