Question

Load Bearing Walls - How To Determine?


I just found out that there is heater duct work running inside of this wall running from the basement to the second floor.

Wouldn't that prove that the wall is a NON-load bearing wall?

Depends on how it was set up. When you say ductwork in the wall, I'm a little confused. The wall is 2x4, yes? Are you saying that there are studbays open from basement to 2nd floor? Lined with sheetmetal or somesuch? Straight up and down in a single bay, or are you making turns inside the wall(s) as well?

If just straight up and down you could double up the studs on either side of such a duct, and use straps on the outside of the plate(s) to hold the wall together and still have the wall be load bearing.

Haven't pulled any drywall off yet to confirm but the house was built in the late 50's so I'm guessing yes.

Not sure what your definition of 'open' is but there are ducts run in the stud bays. The duct in question is further away from the wall on the first floor than where it ends up open on the floor on the second floor.

So if I remove the drywall and find SINGLE studs, then it's not a load bearing wall?

No, not necessarily, it's just what I would have done.

Given everything you've posted so far but without actually being there to see it I would really assume that that is a load bearing wall, and you need support any opening down to the foundation appropriately. Other questions like, is it a shear wall or not should be answered too. After you get things opened up, call an engineer over and get their opinion. It'll cost something now, but in the long run it'll save you money and headache if you make the wrong assumptions now.

I was always told that shear walls use plywood instead of drywall, or plywood and drywall. I don't know if that's true or not but this wall has just drywall on both sides. No metal bracing, no bolts holding down sole plate, etc. so I'm guessing it's not a shear wall.

well, unless the drywall is off you wont know if they used cut in bracings or not. Couple of ways to do this but all will be readily apparent when all the drywall is off. Basically if there is any wood running diagonally, it's being braced.

Most places won't let you do this sort of bracing any more, have to use ply. If you open up the wall and find this stuff, you'll have to put in ply to pass an inspection.

Couldn't I tell by how thick the wall is? From those pictures it appears that the braced wall is thicker. The wall in question is regular size (5 1/8 including drywall).

A shear wall can have a brace that is 'let in' meaning it is flush to the studs, or blocked. So it is no thicker.

Here the 'regular size' for an interior wall is 4& 1/2"

vpap,

I'd recommend starting your own thread. Get's less confusing.

No, because with let-ins, the studs are notched to allow the bracing to sit flush with the face of the studs. Also, there are metal products that simply sit on top of the studs and under the drywall.

At 5 1/8 inches that would indicate rough full 2" x 4" studs. many of the first planed ones were 1 5/8" x 3 5/8". I was told by old lumbermen this was because rough lumber was not consistent in dimension. My suspicion is that with sizes now 1 1/2" x 7 or 9 or? and 1/4" that we now need 2 x 12's instead of 2 x 10's. If you know a friendly builder or carpenter, I would have them look at it and tell you what you do have. Any good tradesman will know enough to tell if you need an engineer, but for less.
