AS/NZS 1170.2:2011 identify eight individual wind regions for Australia, with regionally specific M_d and V_R values which can be applied to calculate the directional wind speed. Given the vast expanse of Australia and various wind hazards in both cyclonic and non-cyclonic wind areas, it is essential to accurately quantify current and future wind risk that is representative of the local wind climate. As such, this study compares the M_d component of the AS/NZS 1170.2:2011 standards for four wind regions (A1, A4, B and C), with observed wind data (4 stations per wind region) - see Figure 1 for more details. Findings suggest that the wind regions analysed do not adequately represent the wind climates of the stations considered within each wind region. For example, while AS/NZS 1170.2:2011 assume that the same directional wind multipliers should apply for Perth and Adelaide, we show that the prevailing direction of the strongest wind gusts (≥99.9^th percentile) varies considerably between stations. Using station data to model M_d suggests that AS/NZS 1170.2:2011 can underestimate wind risk for region A1 (70% of cases) and overestimate between 62-77% of cases for regions A4, B and C. These results highlight some inadequacies with AS/NZS 1170.2:2011 and suggests more regionally-specific wind direction multipliers that are more indicative of local wind climates are required.]]> Thu 29 Oct 2020 13:27:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28267 Sat 24 Mar 2018 07:28:35 AEDT ]]>
