How do you calculate wind uplift per IBC/ASCE 7 for "open" structure
How do you calculate wind uplift per IBC/ASCE 7 for "open" structure
(OP)
The only provision for open structures for Method 2 (components & cladding, h<60')in the ASCE 7 is Eq. 6-25 which appears to be valid for only wind loads acting perpendicular to the surface (walls). Figure 6-5 gives GCpi values for open (and closed and partially enclosed) buildings, but nowhere to be found is a Figure that gives GCp values for open structures. I'm guessing that I'm supposed to use the proper Figure for enclosed/partially enclosed buildings to determine GCp for the appropriate building/roof type and use that in Equation 6-22 with GCpi=0? Or do open structures not have wind uplift?
Thanks.
Thanks.

By definition in ASCE 7, components and cladding are not applicable open structures, thus you must use MWFRS coefficients for all parts of an open structure.
