Shouldn't a hinged end condition prevent the beam from carrying a moment? If the beam is carying a distributed load then it will have a bending moment distribution along the span though zero at the ends if it is hinged. Otherwise it should not have a moment
I didn't think trusses worked at all. Do they?
You should fire up Geostar - you can do this whole thing in about an hour. Essentially you put in all the key points (every connection essentially) where the , then put in lines where the beams go. Mesh the beams and you can contol the end fixity. When you are meshing the beams there is a third point required to orient the beams cross section and there is a plotting option to show the directions. The stuff works in Geostar and it won't take that long to do it.
It would be nice if the stuff worked with something else other than rigid connections though. They should grey them out when the stuff doesn't work.
