  • 1.  Perforated aluminum panel design

    Posted 01-28-2021 02:27 PM
    Hello, Does anyone know of any good design guides or design data or textbooks that cover the design and analysis of perforated aluminum panels?  i suppose there would be a reduction in wind pressures since the panel has perforations.  I suppose the perforations also cause a reduction in the allowable stress and also an increase in deflection.  So I'm wondering where can I find some data/answers on these questions?  I have found there are a few good references in ASCE 7-16 Chapter C30 (Yes, that's the commentary) and wonder how to get a copy of some of these considering most are several years old.  Thanks for any help you can give!

    ASCE 7 Figure 29.3-1 Notes 1 & 2 may be a good start.  Note 2 includes a force reduction factor based on ratio of solid area to gross area if the openings are more than 30% of gross area.
