The main problem I encountered when modeling as a truss member is the fact that I also need to model the sag of the cables. The problem is that when I model the sag and discretize the continuous parabolic shape of the cable into a series of straight elements and make them axial only members...
I am looking to model traffic signal span wire structures using SAP2000 and am wondering what is the best way to model cable elements? I first attempted to model as frame elements and applied moment releases at the ends of members. This lead to errors at joints between members along the span.
