Wind Load on Canopies
Wind Load on Canopies
(OP)
Can anyone help me out and tell me where I might find information on the component and cladding wind load on canopies? Specifically, I have a canopy with a cold-formed steel framed soffit and a structural steel framed roof with metal decking. I have designed the structure assuming an open building. I am looking for the wind pressure on the cold-formed steel soffit. ASCE 7 very clearly states that you can separate the Cn value and use only portion acting on the portion of roof you're designing (i.e. the soffit or roof decking). It says this, but doesn't tell you how to do it or what portion of Cn is from the roof and what portion is from the soffit. Does anyone have a reference for this?
I know that I can conservatively just use Cn, but I would like to see what the value is for each surface.
Thanks.

peinapod....what version of ASCE 7 are you using?
Canopies have been treated somewhat differently in ASCE 7 with various revisions (as have other structures!). How are you defining your soffit? Is it an entire underslung "ceiling" or is it confined to some portion of the edge of the canopy?
