I'm adding a partition wall in the basement. It will be directly under a laminated beam, which is supported by lolly columns; the wall will enclose the columns. So the wall is not structural, just a divider.
Question: to meet code, do I need a top plate under the beam or can I nail the 2x4s directly to the underside of the laminated beam?
(I'[ve already done a small part of the wall and hope I don't have to start over.)
