Design Pressure of Architectural Perforated Panels 5

[kranic24]

I'm looking for suggestions on the "correct" wind pressure to apply to perforated aluminum panels acting as cladding. In particular, the panels that are installed at corners of a building or even wrap around a building.

Does anyone have technical documents or case studies that prove effects of certain hole patterns on perf panels?

My engineering judgement tells me that you cannot develop negative wind pressure with perforated panels at the corner if the percent open is large enough. However, I am unable to determine what percent open I would need to eliminate the negative pressure.

Thanks for your suggestions or any documents to support your response.

Without wind tunnel testing, I would assume it as a solid panel. Who knows, the pressure may be even greater than solid. Aerodynamics can be counter-intuitve. Kind of like pickup trucks are more aerodynamic with the tailgate up.
