Wind Loading on Elevated Structure on Open Framing
Wind Loading on Elevated Structure on Open Framing
(OP)
Does anyone have suggestions on how to deal with wind loading on an elevated enclosed structure supported on open framing? ASCE 7 does not seem to address this case?

This would be the end of most cases. Other issues to check for more complicated cases would be wind vortex shedding, aerodynamic effects, maybe a set of time history analyses based on some measured or thought to be realistic set of forces. Specialty wind tunnel houses will deliver state of the art loadings, computational fluid dynamics seems not to be reliable enough at the time being.

I decided to use ASCE 7, Figure 6-20, but only cases A and B. It seems Case C is accounting for the decrease in suction on the leeward side of a sign or wall. Since my structure wouldn't have this condition, I ignored Case C.
