I'm redoing my basement and came across a 2X8 joist that was notched
at some point in the past.It is notched approx It is the last joist
before the outside sill plate. As you can see it is close to the
steel beam. What is the best way to repair it or strengthen it? I was
thinking put another piece of 2X8 next to it, one end resting on the
beam and extending a good 2 feet past the notch, fastening it with
bolts and washers. Any inputs appreciated.

Considering you have a tile floor above it and it hasn't cracked I
wouldn't
mess with it to much..Glue and lag a couple of sisters if you'll sleep
better and move on...

I still use the term 'lag', also, when the state of the art has passed
them by. Nowadays there would be very few situations where I'd reach
for a lag (and the drill to bore a pilot), instead of using self-
drilling structural screws that can be driven with an impact in a
couple of seconds.

In the OP's situation I'd rather have more smaller fasteners that were
easier to install, than a few larger ones that were more onerous. In
the day sisters were simply nailed and they held just fine. Now
everything is glued. Either glue or structural screws would be fine
by themselves, but you need the clamping pressure of the screws if
you're going to glue, so...

Another thing about lags - their maximum diameter is restricted to 1/4
of the wood thickness that the business end is buried in - in this
case a 2x would allow a 3/8" lag. Lags are notoriously crappy metal,
made in places where lag guilds never took off, and their load
capacity is not all that much greater than other choices such as
common nails and structural screws, which are easier to install.

There's really not a lot of load on a typical floor joist. Figure a
12' span and 16" OC with a 40# live load, and that's about 640# total
for the full span. A 10d common nail can take about 70# in shear, so
we're not talking about a lot of load, fasteners or concern.
Particularly since the OP's joist has been like that for decades.

One caveat - make it pretty. Even if the repair is a straightforward
one and not structurally critical, a sketchy looking repair will raise
more flags when the house is sold. So make it a neat, workmanlike
job.

Wouldn't lag screws be "gentler" on the tile floor above than either a
hammer or an impact wrench?

Drilling with a standard drill and using a rachet to drive the lags
wouldn't subject the grout or tile to any excessive vibration.

I'm just sayin'...



EXACTLY...
