Masonry Deflection Criteria For OUT-OF-PLANE Bending
Masonry Deflection Criteria For OUT-OF-PLANE Bending
(OP)
Does anyone know where the out-of-plane masonry wall deflection criteria are specified or discussed in the code, i.e. ACI 530 (any year), or IBC (any year)?
Any help will be greatly appreciated, thanks.

Note F, from table 1604.3 minimizes offers some relief from the stringent L/600 criteria, but even L/420 (.7 x L/600) for out of plane deflections seems a bit excessive.
Thanks again, and I'm still reading up on the matter.

Building drift is another matter. For drift, you could use L/240 from IBC2003 Table 1604.3 for "Exterior walls and interior partitions:
With brittle finishes" and modify the wind loading by 0.7 per footnote F. However, we use L/360 with service loads (0.7 or 0.75) for drift.

"brick veneer/steel stud walls" states:
"The allowable out of plane deflection of studs should be restricted to L/600 using service loads."
This is to reduce cracking and water penetration.
