RE: Wind & Expanded metal mesh

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Keep in mind that flying debris could change a 50% open to a 100% closed
mesh. Also keep in mind that someone in the future may decide to change the
architectural features and once again 50% open becomes 100% closed.

Subject: Wind & Expanded metal mesh

I will be designing some "eyebrows" that cantilever approx 4' out from the
face of a concrete tilt-up wall.  The architect will be covering them in
expanded metal mesh that is supported by steel framing.  If the expanded
metal mesh is 50% open, can I reduce the wind loads (especially uplift)
applied to it, and if so by how much?  How about if the mesh is 90% open?
Is there any references or good sources on something like this?
Thanks in advance
