partially enclosed vs enclosed
(OP)
I am trying to determine if my large warehouse I am designing is classified as "enclosed" or "partially enclosed." There are some very large overhead doors in the project all in a row along one wall. Do you consider overhead door so be an "opening?"

It says holes in the building envelope which are designed as "open" during a wind event. I would hope that during a 90 mph wind event, one would want to close the doors. Are we suppose to assume all doors are open?

If you consider the windows and doors as closed during a storm, and the building is thus classified as enclosed, the doors and windows need to be able to take the impact.
If the storm hits and the openings blow out, will the building be "open"? If the answer is yes, and you want to design as "enclosed", you need to specify impact resistant doors and windows.
An alternative in coastal regions (at least in the residential industry) is to have plywood to cover each opening on the premises. If the builder does not install impact resistant (which they typically don't because of the cost), they must provide plywood to cover the openings before a storm.

I agree with hokie66.

For very large doors hangar type doors, I have read about pressure leakage and the partially enclosed assumption is more realistic. I think this suggestion may also be found in the ASCE commentary.
