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?
