Subject: Wind Uplift on Footings

Am I hallucinating or is there a provision in the UBC for a F.S.>1.5 against
uplift?

For some reason, I can't find that requirement. I found it for sliding and
overturning relative to retaining walls, but not uplift on footings. I'm
reviewing shop drawings for a lightweight shade structure.

TIA,

T. William (Bill) Allen, S.E.
