Some Of Yall Construction Gurus......

Just clean out all the junk in there and you won't need to add a room.

Well, that is part of the plan. I should have known it would be used for storage when I had it built. A good storage building will help. I also want to put a mezzanine across the back. Maybe before I'm dead. Probably not.

Ok so my shop is 24 wide and 28 long. Will a two wide 2x12 beam span 28 feet and hold the exterior wall of the shop up? It's just a simple metal shop. That side wall on the left is the wall in question. View attachment 1716471542

you can always reinforce it with 1/4'' metal the full length , bolted all the way thru both beams...I did on a carport I built with 2x8`s...

Yall are losing me with this LVL stuff.

LVL is another term for glue/lam

I'm going to suggest very seriously talking to the company who engineered that building. The outer skin is part of the structure on them just like a pole barn. If you take it off to open it up, you will alter the parameters for which is was designed and it could compromise the structural design. Might never be a problem, or the first high wind situation might blow it down.

Not an issue at all. I sold these buildings for a year and they use the exact same frames for the open sided carports as they do for the fully enclosed garages. As long as he has his new beam supported properly and fastens the existing rafters to the beam, he’ll never have a problem.

Two 2x12 will not span 28’ with a load on it, 3 might tho. Assuming you can even find 2x12 28’ long. They would need to be Ponderosa pine, Southern Yellow pine, or Douglas Fir to even consider it. I would assume that you want to cut all of the vertical supports to about 1’ from the top to leave the radius of the roof intact ant the eaves, and rest them on top of the header. A shoe on those would probably be necessary to mount them to the beam, you could probably fab that to go inside the down drop of those legs, use a pass through bolt to hold them to the leg, mount a plate on the bottom and fasten them through the header by drilling holes in them for screws. If you don’t mind a post in the span, then yes, 2 would hold the span with a post. You will still need SYP, Ponderosa or Doug Fir as you will not find regular SPF 2x12 that long. With a post you wouldn’t need one long piece, you could use 14’ lumber and join them on top of the post.

I myself would use 2 16” LVL’s, I believe they would free span the entire 28’. 2) 18” LVL definetely would.

Naw, I'm talking about making a staggered beam. Glued and bolted together.

Any measurable snow is rare here, although it snowed 24" in our back yard at the house I was raised in in Macon in 1973. Keep in mind, Macon is about 80 miles SOUTH of Atlanta and they didn't get a flake.

Local code will dictate the required snow load, if any, needed in the load calculus.
