Masonry Deflection for Long Horizontal Spans
Masonry Deflection for Long Horizontal Spans
(OP)
Our office is working on a number of banks that have teller drive-thrus with 2 to 4 feet of masonry veneer. On some of the jobs, the spans for the supporting beams are 50 feet long. If we size these beams for L/600, we get a huge member that seems excessive. Is there a differnet guideline to follow for this situation, or do we need to use the L/600 tolerance?

I heard an ACI speaker once say the 0.3" was added after complaints had been made that on long spans you can see the vertical displacement too much. Not that it cracks the masonry.
Sounds like you need more supports.
