Australian Building Code Formula for Wind
(OP)
Does anyone know the formula in the Australian Building Code for wind pressure on high rise building cladding?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Australian Building Code Formula for Wind
You would find it in the Australian Wind Loading Code, AS1170.2.!

ajk1, you may also want to get a copy of the commentary (which is a separate book) and the general loading code 1170.1? as this will contain some relevant information.
The wind loads are applied without factors but different return factors are used depending on the type of structure. Anything from 1 in 100 year return to 1 in 2000 years. Serviceability calculations are generally based on 1 in 20 year return. This information is contained in a chart in the building code of Australia or I believe it may be in As1170.1.
Components and cladding loads are obtained by factoring up the normal wind pressures in certain areas rather than using separate tables.
generally is is not that different from other major wind codes once you get to understand it.

When you bang a 1.5 factor onto the 50yr wind in NBCC it will result in something similar to the Aussie standards.
Personally I am still using a 20yr return period for serviceability design (depite the post I started many years back which suggests a 25yr event should be used thread744-237727: Serviceability Wind Events...Is it 20yr or 25yr). A 20yr wind is still a category 1 cyclone for the southerners and category 3 cyclone for our friends in the tropics. Think of cyclone Winifred as being a serviceability wind event!!
A cyclone is a clockwise spinning hurricane.
