I am about to start gutting my chateau, in preperation for the addition off the back of the house. Gable roof, 8-12 pitch, 2×6 rafters 16″ OC.
I have a wall in the center of a 26′ span that the ceiling joist break on. I want to remove part of the wall for an open stairwell and spindles.
Is it just a matter of getting longer ceiling joists and splitting them on the opposite wall on the other side of the stairs? Approx. 42″ from center of the house.
I want to leave the orginal CJ’s in place, using angle iron and lags to carry the splice that used to bear on a wall. I am trying to avoid a beam that is in the room below the joists.
Maybe 9.5″ full length LVL’s through bolted to turn the rafters into a hillbilly truss?
Whatcho think?

put the header above the joists in the attic.
Support it to the waall ends ( which you obviously support with extra jack studds to transferr loadd to below)
then use simpson hardware to hang the existing c joist from it

Sounds good to me, big header and over sized strap hangers. THA 29's or something along those lines.
The span of the header would be roughly 20'. Only load would on it would be dead load.
Thanks for the info.
All of that is omplicated by another issue.
The cieling joists are probabl;y fine to support the dead load at that span, BUT
the fact you want to lead a stair up there presumes that you are converting to storage or some use that requires DESIGN THAT ALLOWS FOR LIVE LOADS. so you need to do some other upgrading

This a stairwell to the basement, the existing stairs are outside. You have to go outside to get into the basment and do laundry. Cold in my neck of the woods in the winter.
The attic space is staying as is.
2x6 rafters doesn't give you much room for R=38 insulation.
I am not removing the ceiling joists or vaulting the ceiling. I wanted to remove part of the wall for an open stairwell to the basement.
I deal with trusses on a daily basis, rafters occaionally. I was looking for advice about the spliced ceiling joists. I thought of a floating header, but just wasn't sure if that was an accepted practice for rafters.
