Working on design of some perforated architectural wall panels enclosing a parking garage podium for a high rise structure and trying to determine whether the design wind pressure per ASCE 7 can be reduced based on the percent open area. ASCE 7 doesn't really address the issue - the closest I could find was 30.1.5, but that section essentially avoids the issue and references "approved test data or recognized literature".
I understand that this is a complex phenomenon given drag and aerodynamic effects for various hole patterns, but this is also a very common application in building envelope applications so I would think that there must be some resources or information out there to provide more guidance. I have reviewed the IPA Perforated Metals Handbook - it was useful for determining reduced E and S values based on percent open area, but does not address design wind pressures very well.
I also came across the thread noted in the subject line - Trenno noted that Australian codes allow a reduction in wind pressure, but did not provide a direct reference for that information. Does anyone know where that may be found? I have been searching for it online, but no luck so far...
