Perforated Plate Under Out of Plane Load

[dreber]

Using perforated plate cladding seems to be becoming more and more common. When you are dealing with perforated plates under wind loads? How do you perform your analysis? I'm less concerned with developing the loads and more concerned with assessing load capacity and expected service level deflection.

I found this article which would seem to be a pretty good start.

Anyone have any examples they care to share?

How about this?

well nowaday FE does it all
Did you try making FE Model ?

You just calculate it as a plate (possibly with membrane action) having an equivalent elastic modulus and strength : google equivalent strength of a perforated plate

I did a design for an RTU windscreen a few years ago, and the perforated plate manufacturer provided section properties and load-span tables. I attached them for reference:
