Facade up and down tolerance as per AISC Code of Practice

[SuG89]

Hello,
I have a steel-glass structural glazing which is dead load supported by the building roof steel beams. I looked into the AISC Code of Standard Practice 2005 and AISC Design Guide #22 for information on facade up/down tolerance at the top connection but didn't find it. Could anyone please let me know where to look for this information?
Regards,
Su
