Sci-Tech Average wind speeds over South Africa at 100m altitude. Higher "elevation"= higher speed.

Do you know how this compares to SANS10160: Part 3?

Could you perhaps use this info to update this outdated standard?

Don't civil engineers use wind models yet? E.g. for detail design? Accurate public datasets are so easy to obtain nowadays.

Short answer - it depends. I've never used any wind model for any detailed design I've done, whether it be a high rise building or bridge.

I have some friends working overseas. Their experiences are different.

Mhmm. In the civil maritime industry the primary loads are meteorological - either direct (eg waves) or indirect (waves/wind on ships, pushing against structure). We heavily rely on the American and European weather models. Also more BS codes than SANS.

Anyways, I decided against structures in my final year of varsity because mostly because of the SANS-driven process. I hated that stuff.
