RE: Wind Uplift on Footings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Not sure about the 1.5 factor but UBC 1621.1 Requires that the base
overturning moment from wind shall not exceed 2/3 of the dead load
resisting moment.

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,
