Isn't pole barn trusses built differently than a standard truss, or are they the same? I was thinking they had a heavier bottom chord.
The trusses neither know nor care if they are sitting on studs or posts. The issue is the design requirements for the trusses - spacing, attic storage, ceiling, and ag vs. inhabited use. In my case I was allowed to specify agricultural-use trusses on 4ft centers.
I'm thinking I heard that the pole barn trusses are larger because they are sitting on the post and have a further spacing than your standard truss sitting on a wall. Most pole barns don't have spacing every 2'. They are spaced farther apart, then use 2xs set on top of the trusses for the sheeting to be fastened to. At least around here that is what I see. Hardly ever do I see a pole barn with trusses set at 2'
