But in this case would it matter? Serious question, I'm no structural
With a 2 x 8 sistered across the notch, extending let's say 2 feet on
each side, and then glued and lagged in, let's say, 4 (6?) places on
both sides of the notch wouldn't that be more than enough to fix the
Would bolts really add anything worth considering or would they amount
Of course, that's not to say that bolts wouldn't actually be easier to
You say you have the walls opened. If this is in a wall, simply support it on
both sides with studs.
If it hasn't gone anywhere in 30 years, it's unlikely to now. However, I'd do
something about it too.
That close to center beam, and to the fully-supported joist on outside
wall, unlikely to fail catastrophically. But just on general principles,
I'd sister it anyway. From over the beam to maybe 18-24 inches past the
notch. A couple 16s to baste it in place, then some staggered carriage
bolts on each end. If that isn't possible, then a 2x4 or steel strap
lagged into the bottom of the joist to take the stress off of the cut
section. Unless a 4-foot level on the floor upstairs shows any sag, I
wouldn't even bother to jack it. Hard to say what it was for, without
inspecting the space for other clues, like on the outside wall. Maybe a
long-gone oil fill line?
I've seen worse, in more critical locations. Held fine for years, then
one day somebody walks through carrying a piano, and 'crack'. Carpenters
have long been of the opinion that plumbers and electricians should be
prohibited by law from owning sawzalls.
By this, do you mean that the gray object slightly closer to the
camera than the notched beam is a structural steel beam? If it's a
full length beam that the flooring above sits on, then I'm not sure
the wood beam is worth worrying about. I would ask for other opinions
after answering that question though. I'm no engineer.
Is the "beam" you are referring to in the lower left of the picture
right above the yellow romex that loops to bottom of the picture?
If so, why does it look like wood? It looks like it's a piece of wood
with possibly a steel plate attached to the face of it.
Not that that has anything to do with the repair of the joist. It's
just that it doesn't look like a "beam", at least not to me.
Am I missing something?
Oh...I see it now. It's an I-beam and that bundle of wires runs under
the top horizontal.
I didn't notice the rust on the vertical part until just now.
I wonder why they used a 2 x 4 on top of it. Just seems like something
that could crush of a joist was positioned on a soft spot. In my house
they set the ends of the beam in a bed of concrete to get it to a
height where the joists rest right on the beam.
