Light gauge exterior wall overhang
Light gauge exterior wall overhang
(OP)
I've come across a question from contractors a couple times which I don't have a clear answer for. Many time a light gauge exterior wall will slightly overhang past the edge of an elevated slab. Usually its an inch or so, so no big deal. I've had the question raised about what the maximum overhang is. I know that using PAF's has edge distance minimums and that controls for fastening into concrete. However just pertaining to the wall its self assuming a normal one story wall what would be the limiting factor for overhang. Would you look at the cross sectional area of the stud and the amount of bearing they have? I'm sure there's got to be some kind of local crippling or some thing. For instance I have a particular location where I am fastening a LG wall to structural steel so the PAF edge distance isnt a problem but there are only leaving me like 2 inches of bearing. Not sure how to check that other than engineering judgment.

I recently reviewed a submittal where studs were supporting 0.6" form deck above with no track and the deck flutes running perpendicular to the stud webs. I asked about local buckling as it seemed to me that all the load would be delivered to just a couple of spots on the studs where there was actual contact. They thought I was nuts and I'm quite sure that they still do. It's interesting how specialists in a field eventually stop thinking about that field's idiosyncrasies. It just morphs into accepted dogma.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
