I am attempting to do a structuralanalysis of a truss with gussets. I have modeled one with only beams where the endpoints meet and that runs fine.
I wanted to model the gussets as shells where the beam ends don't meet and are welded to the gussets. When I run the analysis I get the following result where some of the gussets are not joined together or with the beams (see the bottom right gussets and how far they are deformed. They are all modeled on the same planes so they are aligned properly. I tried connecting them with rigid connections and welds but I can't seem to get the beam to connect to the shells.
If anyone else has done this type of thing before how did you do it? Should I do just a beam analysis and use beam releases to allow the beams to rotate in the directions normal to the gusset? Or should I make shells of the tubes and do a full shell model?
