Foundation for brick masonry veneer
(OP)
I have a 3 story building that has floor heights of 11'-3", 15'-3" and 10'-0" and the architect is wanting to put a brick veneer on the building. It will exceed the 30' requirement for wood backing. He is wanting to use load bearing masonry at the bottom floor and then attach a steel lintel angle to the top of the masonry wall and then go up 30' from there. Would you consider the steel lintel angle the noncombustible structural support or would you still make them put in a relieve angle at the top floor?
If I make them put in the relief angle, can you attach the angle to the wood?

The main reason for the relief angles is the differential volume change is because the clay brick has a long term expansion and the wood has a long term shrinkage/creep resulting in detail problems and maintenance costs. Both steel and concrete/masonry have lesser changes.

Generally we don't use fire protection on steel relieving angles but that may be different where you practice.
