How to apply Wind Load on Domes to AS 1170.2 ?

[atef81]

I am designing a structure that has 3 domes.
I need to apply wind load on the domes to Australian Standard AS1170.2

Can someone please guide me to what's the best approach?
If AS1170.2 does not clearly cover this situation, what alternatives can I use?

I modelled the structure in Space Gass and will be dividing the loads on members manually.

Thanks in advance.

AS 1170.2 Appendix C, C2 Buildings with Curved Roofs, includes domed roofs. Using this clause for domed roofs will be conservative relative to an arch, but probably ok for the relative size of these domes.

There is some commentary in AWES-HB-001-2012, 4.1.2 Curved roofs. Mostly references to some wind tunnel testing and cfd work that was done in this space. Anything published by Holmes and Ginger would be worth a search.
