Beaufort wind speed chart, with AS4055 wind speed classifications for comparison, and wind speeds of some Australian cyclones. Useful for comparison, when assessing serviceability wind speeds to choose, and also strength limit. Noting AS1170 indicates waveheight increases surface roughness thus do not have terrain category 1 or 2 in coastal regions at ultimate limit state, rather these terrains categories are relevant at lower serviceability wind speeds. Also useful for determine construction loads, and when factory doors likely to be closed, and wind speeds make work difficult.
