Table Notes
  1. The peak gust has an equivalent moving average time of approximately 0.2 s (Holmes and Ginger, 2012).
  2. Values for V1 have not been calculated by the formular for VR in the Australian regions.
  3. For ultimate or serviceability limit states, refer to the National Construction Code (Australia) or AS/NZS 1170.0 for information on values of importance level and annual probability of exceedance appropriate for the design of structures. For buildings in townships in cyclonic regions, users should consider overall risk to a community when selecting importance levels.
  4. For Regions C and D, only the maximum values for the region are tabulated. Lower values of VR may apply in those regions, depending on the distance of the site from the smooth coastline.
