I'm currently modeling a full, standard bow truss in Risa 3D but would like to model and load it as a 2D model. I wasn't sure if anyone recommended any types of 2D modeling software that is fairly easy to learn as well as would produce good results. Being free would also be very nice. Any...
Also, when the members are pinned we are getting sensible stresses but zero deflections which can't be right. Then when free we are getting both stresses and deflections that seem much too high.
Ok thanks, the sub-meshing seemed to help a bit. The problem areas still seem to be on the truss members themselves. In Risa, are nodes on a truss assumed to be pinned, free, fixed, etc. I think this may be a problem along with the I and J releases. Any help with those two areas would be...
I am currently modeling a 9 truss hangar and am having some problems with somewhat large deflections and very large member stresses. I currently have the end boundaries pinned and have also tried having them completely fixed as well as free. I wasn't sure if anyone has any idea how the truss...
