I recently built a workshop (2x4 construction for the walls) with 16' wide by 24' deep dimensions. I want to build a storage mezzanine that spans the front 16' wide by 8' deep section above the garage door but I am unsure of how to do this without installing a post along the span.
Any suggestions on how to build this? I need an adequate "floor joist" system that will support the load above, on 3/4" T&G plywood, without sagging across the 16' span. I was planning on running 2x?'s across the 8' span, 16" O.C., but this also ads to the weight that has to be supported on each end.
The roof above is conventional "A-frame" construction, so I don't think it is wise to attach a load to this, though a friend of mine did it on an 18 foot span, using a cable to tie the centre of the shop to the roof. I'm skeptical on this one.
If anyone knows of a formula for calculating loads for this thing, I'd be interested.
