Something that was bugging me at 5pm this afternoon - getting an idea of the differences in wind speeds and wind loads when comparing Australia Vs Europe.
The problem arises in how basic wind velocities are calculated... so attempting to compare basic service winds at 10m height in open terrain...
V50 (1:50) 3 second gust wind in Melbourne is 39 m/s.
V50 (1:50) 10 minute average wind in London is 21.5 m/s.
I understand there are a few different methods to convert/compare these numbers. Is there a basic or conservative factor I can apply to compare them?
When I have time, I'll do a side by side calculation to see if differences come out in the region/shape/area coefficients.
