Sorry, Paul, I can't answer you right now... all my safe load tables, etc are at work
.
A bit more info is required also...
I assume this is for an obs (what else????
)...
Is your pier independent of the floor? (So we don't need to account for the weight of the scope, etc Silly question, I know!
).
How much is the weight of the obs building/shed you plan to put on it? I assume the walls are around the perimeter only?
If you know your terrain category and design wind speed, that will help, but if not I'm sure assumed figures for Oberon will be conservative!
Hopefully someone else will jump in with a "my obs has xyz sections under it" and save me some work next week...
Al.
