Does this framing look right to you?

Hoping I can put my mind at ease with this post.

I'm no carpenter, but cutting into 2x12 top chords to run these connectors doesn't seem right to me. Is this standard practice for a pole building truss? Is there anything to be concerned with insofar as snow loads or sagging later in its life? This is on both sides of the truss.

Not sure, but it looks like the 2x12s were butted up to 2x6s or 2x8s. Maybe the stud top plates aren't wide enough for the 2x12s? Can't say that I've ever seen this before.

They appear to be built that way. If they were built that way, there's a reason for it and I would bet money they have a stamp on the truss plan.

Is that center area up stairs a clear area…cause they do that when there is a longer unsupported area they need to span. Seen it here a bunch. If the center area is not clear (like for a loft or room)…then there is something else the design is trying to accomplish.

Its a clear area yes. 20ft wide "catwalk". Good thinking on the truss plan idea...in digging back through years of email, I found it and sure enough, they are designed that and of course, stamped. Whew. The building just got finished...I'll posting up a story on it soon. Thanks Gents!

What are the truss dimensions? I’m no truss builder and it does look unusual but I bet it’s fine

you should have had specs & drawings with the trusses? if they are engineered & stamped, you're good to go.

The lower chord on my attic trusses are also stepped.

THose are engineered trusses and they were made that way. Nothing wrong and everything is perfect. They should have left all the truss papers that came with the truss package. It will have drawings of every truss so you can verify nothing was modified onsite. Inspector will need to see those papers.

When I had this built…I had a spec. of 200lbs live load. I hate springy floors. The bottom cord is 2x12 and was also designed to handle a 1 Ton hoist track below…so certain areas are doubled…and several are quadrupled up. I specifically reviewed the truss design and had them make all the cord sizes constant because I am in snow country as well and wanted less deflection in the sheathing structure.

They often need to mend pieces like that together (with mending plates, as in your picture) when the dimension of the member is longer than the wood comes from the mill. I assume you have a long clear span in the middle, (that we can't see in the pictures) which is why they had to choose one section larger than the other.

You guys sure know how to make a guy feel at ease. Glad to hear the engineering behind the idea and glad to see its been done before with success. It is all in the plan, but today was the first time upstairs in the loft area and just wasn't expecting it.

Looking forward to seeing another build out of Mass! My trusses are built the same way. Tough to see in that pic, but they step up in size from 2x4 to 2x6. The bottom plate does the same for the attic section of the truss.
