Wind Loads on Open Buildings in ASCE-7
Wind Loads on Open Buildings in ASCE-7
(OP)
I posed this question in Sturtural-other, but this looks like the better forum. Please excuse the duplication, but my question is how to determine wind loads on open buildings with other than monoslope roofs. ASCE-7 Chapter 6 seems to sidestep this issue entirely, as does the "Guide to ...". I assume I've missed something. I'm making a post mid-life change in area of specialization, and any help is appreciated.





RE: Wind Loads on Open Buildings in ASCE-7
For open buildings, a coefficient of +1.05 shall be applied to the covered areas of zones 1 and 5 (windward wall surfaces); a coefficient of -1.05 shall be applied to the covered areas of zones 4 and 6 (leeward wall surfaces).
For wind blowing perpendicular to the frames, generally on the endwalls of the building they stated the following:
A coefficient of 1.8N (N = number of frames) shall be applied to the solid area of the largest frame projected onto a plane normal to the ridge.
Additional information is available but is too voluminous to type here. If you will post your email address, I will email the appropriate pages. Note that these coefficients are based on the old fastest mile wind speeds, so may not be totally correct for use with newere 3-second gust wind speeds, but should get you close.
use a factor of 1.05 on the windward surfaces and a factor of -1.05 on the leeward surface for any
