“inset beam” retrofit with joist hangers ?

[milli...@yahoo.com]

When I removed a load-bearing wall to create an open-concept kitchen/living room, we placed one large LVL beam perpendicular to and under the ceiling joists where the load-bearing wall was and supported the ends. A few years later, I had a contractor do the same to create one large master bedroom. He had to remove the load-bearing wall between the two bedrooms, but instead of putting the LVL beam perpendicular and BELOW the ceiling joists again, he cut into the joists and fitted an LVL up between them (still perpendicular to them), and added joist hangers on the LVL for each of the ceiling joists (i.e. both sides of the LVL). Is there a special name for this type of “inset beam” retrofit?

Maybe "flush beam" as opposed to "exposed beam" ?

Looks like a lot of work just to avoid an exposed beam ;-)

That's it. Yes, a "flush beam". Thank you!

Did he get engineering or he just do it. This sounds pretty shaky to
me.

[milli...@yahoo.com]

Good question, but it was done all good and legit.

It doesn't sound any shakier than doing it exposed to me. Either way the beam has
to carry the load. And joist hangers are routinely used to fasten joists to beams.
There might already be joist hangers holding the two far ends of the joists in the
same way.

It depends on whether there is any computed horizontal load (wall
bowing out).
If you are in a place with a wind code they understand all force is
not down.
Joist hangers have virtually zero side force retention. You only have
the extraction strength of the nails going into the beam.

I call that a shear wall. A non-load-bearing wall that is a shear wall is just as critical, and vertical studs obviously don't transfer force horizontally unless they are well tied.
