Masonry Deflection
Masonry Deflection
(OP)
Does anyone know of a good source for suggested deflection limits for masonry? In particular I am looking at limits for a cantilevered wall.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Does the wall serve an architectural purpose?
How much movement can the connections to this wall tolerate?
Is there a drift limit? Why?
Is there a safety issue connected in any way with it?
How about human sensitivity to it's movement?
Are you looking at deflections in plane or out of plane?
Is this a masonry veneer, or is it a reinforced CMU block wall?
The movement limits for masonry walls are several. And there's alot of discretion in the art of predicting and controlling the behavior.

As far as deflection, probably the architectural finish won't control so long as you detail joints to accomodate rotations well.
Likely more critical is the effect of deflection on the stresses in the steel bent.
It's probably best to model the frame on the computer as well as hand calcs to experiment with the system and understand the limits of restraints and deflections.
The understanding of preliminary study should show you how to get to a final design.

For a new wall.....? Define your tolerence and get a good contractor .
