The attic above my garage has several of these horizontal support beams across the ceiling joists, I assume to keep them from bowing. I’d like to put down plywood across the whole floor without these because they’re a tripping hazard.
Are these supporting pieces necessary? Can they be replaced by plywood and still keep the joists from bowing?
Just to clarify, I’m not referring to the beams holding up the roof, just the non-load-bearing ones.
