Open Structure Wind Design
Open Structure Wind Design
(OP)
I'm looking to design a canopy-type open structure using either arched trusses or a hip framing for the roof. Neither of these scenarios seem to be covered in ASCE 7-05. Does anybody have any suggestions or other references that may help me determine the wind load distribution? Perhaps the Canadian NBC has something?

Can you post a sketch so I can be certain that I have a possible solution?

Aerodynamic shape factors are also provided for frictional drag on exposed members for free roofs, AND attached canopies, awnings and carport roofs are addressed in section D4.
If you want some real-world assistance I'd be happy to help if I'm able. Post your e-mail in the tradition Whatever < AT > Something (DOT) something format and we'll see if we can't get in touch directly.

Look at earlier versions of ASCE 7 for arched roof coefficients over open structures.
