Collar Tie's
Collar Tie's
(OP)
Retired Contractor here.
My question is placement and size of collar ties.
Span is 25'3", 2x6 rafters. I have a "bearing" wall 13'6" from slab to rafters. Roughly 1'off center from 2x8 ridge.
My ties will connect to the wall studs as well as the rafters.
I had planned in the upper 1/3 making it 32" above the plates and a length of approx. 10'
Will this work? and size of ties?
Thank you for any advise.

You can draw out a sketch and it'll help. What was your trade? If you were a framer/carpenter, you should be able to get through the IRC easily enough. Conveniently enough you're in Virginia. So am I, so my references should work well for you. Here's a link to Chapter 8 of the Virginia Residential Code. It has tables that spell out span lengths and required sizes, as well as adjustments depending on variable heights of rafter ties.

I was a framer for many years. I know the code use to state, collar ties in the upper 1/3 of attic space.
I read the code had changed to the lower 1/3 unless designed. Now, I think it may have been the IRC code changed, because from my understanding r802.4.6 states in the upper 1/3, exactly my plan. I realize I will need to sister the rafters.
anyway I will upload the print.
Thank you
