Curved Roof Wind Loading
Curved Roof Wind Loading
(OP)
I have a question relating to the geometric expressions used in appendix C3 of AS1170.2 for buildings with curved roofs. I have a situation unlike those described in the illustrations of this appendix where my building is raised off the ground by a series of columns. Should I be adopting a value for 'h' (denoted as 'the average roof height') from the ground or from the soffit of my raised structure?

It's the average height of the curved section above grade. I would add the distance from ground to be bottom of the columns when figuring your "h" height. Page 64 on the link.
