RE: Re: flag pole deflection

Richard is correct.  The MBMA only says that the lateral drift should be
calculated, and some owners get concerned when the lights sway.  Some of the
manufacturer's of metal buildings use lateral drift limit of h/30 for a 10
year wind.

Since your structure is only subjected to lateral load and a minimal axial

Wow!  This seems high!  I know of quite a few metal buildings which could
never meet this criteria.  :o)
