This may seem like an oxymoron (wall wind loads on an open building), but sometimes this can occur.
I would like to understand which equations to use for elements and system using for MWFRS?
(btw, I'm using Directional - Part 1)
Section 27.4.3 "Open Buildings with ..." sounds like the right approach, but when I review equation (27.4-3) it appears to be aimed at ROOF pressures (due to the use of qh, not qz; & the CN coefficient appears to revolve around roof geometry exclusively)
Section 27.4.1 "Enclosed & Partially Enclosed.."'s equation of (27.4-1) seems like it would make more since once the internal pressure portions are omitted. However the NAME of the section doesn't seem to be supportive of this approach AND the table I would use to derive Cp (Figure 27.4-1) denotes "Enclosed, Partially Enclosed Buildings" (no love for Open structures?).
I've searched around the forum and seems like some designers using the minimum design wind loads (section 27.4.7) but that seems like a cheap way out.
Thanks,
