Torsional effect

[nicola27]

my structure is concrete and I modeled the beams with BeamElementWithHinges. I have not included in the initial analysis of the torsional stiffness in the fiber section and the period was 0.8 [s]. After I inserted the torsion (Ubig) and my period is increased.

you could look at the input files for opensees that navigator creates.
