I will say.. augering 2 more holes on the garage perimeter as a sole support for a beam isn't out of the question.

Yeah I honestly have no idea on what to figure for soil bearing capacity. Let’s just say I could probably build a mortared stone foundation for this garage with all of the rocks I pulled. The charts are very inconsistent.. for example:

Yeah, see billconner’s post. I wouldn’t consider putting a 2x wall on top of a 5” thick slab and no continuous footing with such a load.

Yes.. that’s basically what some are suggesting. This may be my best approach depending on the cost of a TJI.

I appreciate the calculations! I’m going to show my calculations. Let me know if I’m missing something. Let’s keep the 110psf for total load. Mezzanine will be 31’x16’ = 496 sq/ft 496 sq/ft x 110psf = 55,000lbs Now let’s assume I do have headers on each eave end to support 31’ clear span...

A 14” or 16” TJI would be ok height-wise, I would think. I don’t want to lose vertical space in order to maximize headroom above and below. That’s partly why I made this post.. as my piers are already in. They’re a minimum 18-20” in diameter (some pushing 20-24”) and at the required 42” depth...

Ah ok.. I think when you say “glulam” you’re referring to something like an LVL?

I’ve never thought about the TJI spanning the 32’ method.. and I’m intrigued! As to cost effectiveness, I have no idea. I would then have to figure out how to support that steel beam. 24” deep joists, yikes! That seems a little counterproductive if they are indeed that tall.

That’s similar to what I’m imagining. Except there would be an LVL where the bottom chord is. That LVL would then be fastened to the post on each side. Then also supported with a hanger(s) that is fastened to the scissor truss above it.

This mezzanine will essentially be 2 post and truss spaces deep (trusses to sit directly on posts). About 15’.. With that said, could attic trusses be considered? I could probably use 2x8s for floor joists as the span would be cut in half. Again.. they would have to be beefy at 7’7” spacing...

If you look at one of the previous responses with pictures (steel framing), that’s exactly what I’m trying to do. I’m not sure what you mean with the last paragraph. I’m having a hard time picturing what that would look like.

Yes!! Your pictures are exactly what I’m looking to do but with timber framing! That’s why I’m trying to determine the loads that will be imposed on that one particular truss. That truss will be bearing on a 3-ply post on each side. The LVL that is acting as the joist ledger (31’ span) would...

Thanks! I would like 40, but also want to keep in mind overall loads that are imposed on the truss and post. The joists would be running the 15’.. not the 31’. Unless you meant to use the TJI as the ledger beam instead of an LVL?

I want to use scissor trusses in order to have headroom in the mezzanine with a 14ft eave/sidewall height. I think you’re misunderstanding what I’m trying to do, and that’s probably my fault for not explaining it good enough. The LVL will be held up (or, hung?) by/from the truss. The LVL will...

Anyone with a background in structural engineering here? I’ve been debating on the design of my mezzanine before I commit to framing the building. This mezzanine would encompass a portion of the building (roughly 31x15 footprint). Here is the quick and dirty.. - 32x36x14 post frame on...
