Application of ASCE 7 C&C to mesh/open components
Application of ASCE 7 C&C to mesh/open components
(OP)
Am designing for wind loads to mesh paneling that is attached to a high rise. It has approx 50% opacity to wind. I trust that it is best to utilize the Components and Cladding approach utilizing velocity pressure of the height of the building for leeward wind.
My question is: do you apply the Cpe/Cpi factored pressure to only the solid area or do you ignore the 50% opaque part and treat it as a solid panel?
I am confused - the open signs/lattice framework section allows for the use of a solidity ratio to determine an appropriate Cf and apply the calculated pressure to the solid area only. Components and Cladding makes no reference to the area to apply the pressure - solid or gross?

The coefficients in the C&C section of the code take into account the relationship between effective area and pressure coefficients. So whatever design pressure you come out with would be multiplied by the effective area (i.e. 50% in your case).
