AS/NZS 1170.2:2002 - Table D4(A) & Table D4(B)

AS/NZS 1170.2:2002 - Table D4(A) & Table D4(B)

(OP)
The net pressure coefficients are applied for h/d <= 1 (monoslope free roof)

How about h/d>1 ? How can I obtain the net pressure coefficient ?

Thanks

RE: AS/NZS 1170.2:2002 - Table D4(A) & Table D4(B)

Just thinking out aloud, no guarantee that it's true;

With greater height and therefore less ground effect the pressure coefficients are likely to be lower, so the same coefficients can be used but they will be conservative.

RE: AS/NZS 1170.2:2002 - Table D4(A) & Table D4(B)

Good question, AS1170.2 only covers h/d<1.0 as does ASCE7-05. 'Wind loading on Structures' by J.D. Holmes speaks briefly about it but does not say anything about the specific example of when h/d>1. You could try to source some of the reference papers that the code is based on, or you could put it to the code committee and see if you get a response.

What is your h, d and roof slope?
