Double-check your beam elements.
There's something wrong:
  • In the section aggregator for beams, you used the concrete material for Vy and Vz... are you sure? You should use a proper shearforce-sheardeformation, not a compression-only stress-strain law... as you did for the columns.
  • Then you defined hinges at the beam-ends, but you assigned a material in only 1 DOF. It will be singular for all other 5 DOFs.
I don't fully understand what you are trying to do with the beams
