Cp values for open structures with arched roof

Cp values for open structures with arched roof

Hello to all,

I'd like to know what cp values (from what figure or table) should I use for an open structure that has an arched roof.
Figure 27.4-3 seems to give me the information I need, except it says it's for enclosed or partially enclosed structures.

Thanks in advance.

RE: Cp values for open structures with arched roof

I use the external values as applicable for enclosed and partially enclosed (and make note of it with an explanation so it doesn't get rejected by a zealous plan checker) - I run into the same issue when doing canopies and awnings with curved frames quite frequently. I feel comfortable with it and it's never been rejected...maybe someone will prove me wrong! Let's see what the rest of the community says...
