Hello - I have a working truss model of a truss for a covered bridge. We are modifying the design to include intermediate rafters between panel points, so I added the concentrated member forces to the top chord between nodes. Since it's a truss model, the program is not producing a moment. How do I convert the model to a plane frame instead of truss analysis? Can I simply modify the top chord properties somehow? I'd rather not start from scratch here.
