RE: Canopy Roof Wind Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Roger -
  You are correct. The canopy is located at the main entrance of a building
but is structurally independent. Using Lew's advice, I'll analyze as an open
structure with a 20 degree monoslope roof. I'll also analyze as a partially
enclosed structure. I'll probably use a wind design uplift value(s)
somewhere in between.
