Roll Up Doors and ASCE 7-10 Opening Definition
(OP)
The office is discussing whether a roll up door (10x10) for a maintenance bay should be desiged as open or closed during a design wind event. If open, the building becomes partially enclosed. If closed, the building is enclosed. (as per the ASCE 7-10 Building classification definitions) The door will be closed during the off shift hours, and the maintenance bay continually occupied during the on shift hours. Should the door be viewed as open during a design wind event, or may it be considered closed during a design wind event? I would appreciate any opinions on the subject as it appears to be up for interpretation.
Thank you
Thank you

The wind event we design to is a rare occasion, one in which does not happen often and therefore the office building will have their door closed, IMHO.
This factor is the same thing for most structures with operable windows and doors, if all openings were open during a hurricane one may experience local or larger failures. I recall a project of ours where a hanger door was damaged by projectiles/user errors and then the rest of the building began to experience failures (metal roof panels blew off) from the increase in internal pressures due to wind loads.

I believe that I will indeed opt for the partially enclosed classification. Thank you gentlemen for your insite it is well appreciated.
