Lintel Bearing
Lintel Bearing
(OP)
The approach that I see engineers take seems to vary and I have often wonder about this:
How many engineers extend bottom plates to the end of beam lintels?
How many engineers require that the bottom plates extend only to the face of the opening and lintels shall be welded down to bearing plates at each end? If yes, is this because you are designing buildings in a seismic zone or high wind area?
Is your approach the same on both interior and exterior lintels?

RE: Lintel Bearing
I generally assume the plate is just the width of the opening, and does not extend into the support. Of course, the torsion at the end of the lintel (if any) must be resisted, either by welding to a bearing plate, or without a bearing plate, if there is enough dead load coming down from above the end of the lintel.

RE: Lintel Bearing
Our projects are in a non-seismic part of the country. If I was working in a seismic area, I probably would weld them down as Dave Atkins does.
If I do have significant torsion, I am somewhat skeptical that the masonry backup (usually 8" CMU) can actually resist the torsion. I would prefer to attach the torsion resisting lintel to a steel column at each end if necessary.
