Windbreak mesh
Windbreak mesh
(OP)
I've been asked to calculate an overturning load on a mobile structure that will have windbreak mesh on it. I see it quoted as 50% or 60% reduction. Would this be a reasonable approach to say an overall Cp of 0.5? Has anybody any experience of this or know where there are any actual design references. In this case I would like to see a reduced figure rather than take a conservative view of it with a solidity factor of 1. Thanks Mobe

Also: Even if you can justify a lower drag coefficient, I would check the wind on ice load combination in ASCE 7 (or similar check in whatever code you are using) considering the mesh as a solid panel, if of course this mobile structure will see ice. I am sure that would govern in most cases.

There was a scary incident with a huge flag on the suspension cables of the Verrazano Narrows Bridge.
They don't attach flags to it anymore.

As the others have said, use a solid sheet and make your life easier.

I'd agree with this but I'm not an expert in this by any means.
I once had an aerospace engineer friend of mine tell me that the drag on a typical single engine plane wing was lower than that of the cross-wise wing stabilizing cables used on the old Sopwith camel bi-planes.
