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!!
Is this in pitched rafter case is applicable not for truss if I am wrong please correct me.because in case of truss we can consider web member as a support and in that situation we can check deflection between two vertical web member of truss instead defining dj1 of column node and dj2 is apex node of bottom chord truss member
