Residential Girder Detailing 1

[TRAK.Structural]

I have a project where a client wants to remove a portion of an exterior load bearing wall in order to make a large opening to a rear addition. The wall supports the 2nd level floor, roof trusses, and brick veneer. I've seen some threads about brick veneer support with wood as it relates to the code but it's still a little gray to me. See below some options for the detailing. Option #1 is similar to what I see at garage openings in my area, but I don't love the torsion this puts on the girder. Option #2 eliminates (or drastically reduces) torsion but I'm not completely sure if it is technically permitted. Option #3 is similar to #2 but just with a steel beam. The span is 19 feet so #3 may win out just due to load and deflection criteria but I'd like to know how others would approach the detailing to this.

Lastly, does this kind of change warrant cutting in vertical joints to the brick at both sides of the new girder?

I'm curious how the rafters for the low roof get fastened to and supported by the brick veneer in a case like this? Brick veneer is not supposed to support structural loads.

You could stiff-knee up from the ceiling joists.

Good idea. I will try to remember this for future reference, but for some reason I doubt this is how it is usually done. I see this condition all the time with porch roofs and such, and I always wonder how they are connected.

They definitely just screw a ledger to the brick unless it's detailed to go thru.

Brick veneer is not supposed to support structural loads.

It supports itself and transfers lateral load into the MWFRS. I believe you can go 12ft in residential before you need another shelf angle, per the BIA, though two- and three-story houses get built all the time around here without one.

No. I was referring to structural loads from the shed roof rafters as shown in the sketch upthread. Brick veneer is not supposed to support structural loads, like for example a deck ledger board, or in this case, roof rafters.
