Further to my original message of 11/26 and regarding all of your much appreciated advice and comments. Thanks.
Firstly despite Piffins praise of my “written” description I made a big mistake.The floor joists(24″o.c. 2/10’s) are not repeat not hung from the W10x26 steel beam. This beam extends below the ceiling of the garage. The joists are continuous across the beam from sidewall to sidewall. The beam is 22′ long and rests on a 4-2×6 post on one end and and a 6-2×4 post on the other. These posts are on 8″ foundation walls with10″ concrete piers 8′ to 18′ deep positioned directly below the post locations.
There are no garage door openings or headers involved and it seems that the situation described above could provide support for a ridge beam suggested by most of you.
For quijibo: The head room is 13′ 5″ and the room is actually 24′ 9″ wide.
For IdahoDon: The room is 22’6″ long and then extends another 13’0″ at a 35* angle. The 22′ 6′ section is where I want the cathedral ceiling.
For Piffen: What is ” the special hardware from Simpson”? Number please??
For GHR :What is (are) the engineered solution(s) that I “have lots of room for” Could it be the one suggested by Bman? See below.
For Bman: Your ” triangle comprised of the knee-wall stud, floor joist, and a new diagonal member ( which could be metal strapping) sounds like a winner! This is very similar to the “2×4 ( a new diagonal member) connecting rafter to floor joist solution” as per QA on page 98 of FHB June/July 2006.
I prefer this solution even though I will need to take up some flooring. Note that the Engineer providing the answer in this QA is confusing rafter ties with c ollar ties.
New thought:
How about a 13’5″ 2×4 load bearing wall from ridge board to floor down the center of the room?
This may seem a little strange but I want to use this room as a ” trophy room” and need high walls.
If I put knee-walls at 9′ and 5′ on each side I have:
1 – room 9’wide ,2 – “rooms” 3’6″ wide , and no high walls.
If I put a wall down the center and knee-walls at 5′ each side I have:
2- rooms 8’wide, 2- 13′ high walls, and space for bookcases etc. at/in the 5′ knee-walls.
So- What do you all think?
I will be seeing an Engineer. By the way I am an Engineer. Colorado School of Mines. But – a Geological Engineer. Really the best kind by far!

Hunter, take this message and paste it back in your original post. Might help you connect with those that have seen it already and provide info to those who haven't.

They might look something like these, but no way would I attempt to spec a piece of hadware for you. Your engineer can contact Simpson directly and describe what you are attempting, and they will suyggest that he look at such and such products.He can then analise which will do the job and which are more cost effective.
Simpson also has a product choice software download, but I'm not sure if it covers unique situations like yours.
As to the original description, maybe I mis=-interpreted your verbiage.
I like the concept of a high wall supporting the ridge. It can even have a large arch in the center and the upper portion of the wall be built as a box beam to take the place of a ridge beam solid. You would then still have the large feel of an open room, have extra display space, and solve the structural problem. I think it would be important to draw out cross sections to determine whether this would be comfortable to use such space. This is one thing 3D CAD software is really good for with camera walkarounds.
Maybe you just rounded things off in the first posting last week, but I am curious how a 24x24 garage has a nearly 25' room size above it. If the walls do not stack, there may be a way to deal with this without too much trouble. Of course, that is why you need an engineer to see conditions on site. I'm sure you wouldn't spec out a mining shaft without site spcific data now, would you?
Colorado School of Mines? You must know what Coors tastes like then, eh?

You think he was tunneling under the brew room?
LOL, Don't they get three semester hours for swilling there? Actually, you know how dry those engineers are - probably need something wtter than Coors to drink...

I hear tell they designed the first "Rolling Rock", I wonder if their sports teams knickname is the "Gophers" or maybe "Moles"
Yes, I did round things off to start with. The wallsw are stacked. Your Simpson hardware does not look like what I had in mind. Thanks for the reply
Thanks for your reply.
Re: The high wall. We like your idea of the large arch and the box beam but think the arch would take up too much display space. My wife has decided upon a 22' long wall that extends from the ridge board down to 7' above the floor. The wall would be supported by posts at each end and probably one in the center. it would be 2x4 @ 16" O.C. sheathed both sides by 1/2" ply and 3/8" sheetrock - sort of a giant box beam. Building the wall prior to removing the collar ties may be a little tricky but installing a ridge beam would be impossible.
Thanks again for your comments.
