I have a question about how to set-up the design parameters to accurately check the top chord deflection of a pitched truss. The high-point of the truss occurs at the midpoint between the two support columns.
For a flat truss, I would normally define the top chord DJ1 and DJ2 as the two column support nodes. However, for a pitched truss, is it still appropriate to define DJ1 and DJ2 as the column support nodes? Or would I define DJ1 at the column + DJ2 at the high point of the truss, and DJ1 at the high point of the truss + DJ2 at the other column?
Thank you for any clarification that can be offered!!
