Wind Loading on specific members

Wind Loading on specific members

Wind Loading on specific members

(OP)
Now this might be a relatively simple problem to solve, but I've had the most difficult time trying to solve it and CSI tech support... well do they even exist?

1) I'm trying to apply a static wind load (NBCC 2005) to a vertical truss (only to one story).  I only want the wind load to be applied to the exposed truss members.  I understand Imay have to manually create and apply a lateral uniform load, but how will I apply it to those exposed sections?

RE: Wind Loading on specific members

Do you have a completely exposed truss? Meaning is there no cladding? Does the wind load flow between the truss members and out of the building?

RE: Wind Loading on specific members

(OP)
The structure is completely exposed to the elements.  There will be no cladding on the section that I am trying to apply wind load to. It's a simple 3m x 3m open frame with X type cross bracing (think box with an X on all 4 sides), so yes the wind will flow in (through the windward side) and out the leeward side.  

I also had a wall section where there is cladding, but I think the way to go about that is inserting a dummy wall and applying a Cp coefficient to it?  (please correct me if i'm wrong)

your help is much appreciated
