drift limits with storefront

drift limits with storefront

(OP)
I'm working on a building that uses aluminum store front for cladding-lots of glass.  In between the store front sections is metal stud framing.  The top of the storefront framing is about +9'-4" AFF, and the top of the curtain wall is about +18' AFF.  We basically have modules of storefront that are getting inserted into metal stud framing.

How much drift is acceptable at the top of the storefront?  I seem to remember a value of about 1/2" in a 10 year wind.  Thanks.

RE: drift limits with storefront

I would use something on the order of H/400 for 10-year wind.  If your studs are curtain walls only, non-bearing and not LFRS, you can also look into using deflection clips that allow slip for drift as well as vertical deflection.  Then no drift reaches your storefront.
