Wind Load on inside office structure in an airplane hanger
Wind Load on inside office structure in an airplane hanger
(OP)
Looking for some help. I have a mezzanine structure that has an in-plant office structure on the top of the deck system, approximately 12'-6" to deck surface plus a 10'-0 office module wall. The stucture is inside an airplane hanger for the military. ASCE 7-05 calls for a wind speed of 130 mph, near the Gulf Coast water of course. I want to check the mezzanine structure as well as the construction of the office module but I know the structure is used for an office, it's pretty much sheltered from the wind becasue it's inside but when the hanger door is opened what should I be using for the wind load on the walls of the office & mezzanine steel. I need to check the structural mezzanine columns but it doesn't seem practical to calculate a partial enclosed structure exposure "B" with 130 mph in a hanger when the door is opened. Any suggestions or maybe a reference. There is an inplant office below but not attached to the mezzanine structure.

This can be a bit tricky. If the hangar is designed as an enclosed structure, then the office on the inside need on only be checked for 10 psf. If the hangar is designed as a partially enclosed structure (and in my opinion it should be), then I would consider checking the interior partitions for the internal pressure.
For reference, see ASCE 7 commentary, C6.5.11.1, particularly the last two paragraphs of that section.
