Can you give an example of what you want/need?

I want to compile simple 3d model of bar members to get tension compression forces. Further STM "hand"-calcuculations are made.
You can get results like these on the picture , but for such a 3d model it is not possible to have only truss bars . RSA would report it as unstable.
I managed to get similar results, regarding axial forces ,by using bar elastic releases for the upper bars(all but columms).
Using very weak springs you can have a stable structure without having significant bending moments.
