Built-up Wood Columns
Built-up Wood Columns
(OP)
Hey all,
I've always assumed that wall sheathings such as plywood or OSB, if adequately nailed, laterally brace wood columns in walls. What do you guys think and is there a upper limit to that?

NOTE: Remember construction loads! I have seen wood axial members buckle prior to sheathing installation.

I would consider gypboard the same way, but require a greater width of board to use as stiffening. This would apply to wood stud partition walls and bearing walls not used as shear walls.

Not quite sure what you are getting at here, but, for any given width of wall, I would feel more comfortable with using OSB or Plywood than Gypsum for lateral restraint of the weak axis of the load bearing wall studs.

I think that's the point he was making. If you design assuming you have plywood and then later on they decide to get rid of the plywood and forget to tell you.
