How can I obtain the net pressure coefficient ?Thanks RE: AS/NZS 1170.2:2002 - Table D4(A) & Table D4(B) apsix (Structural) 18 May 10 23:55 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.

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?
