Beams

You should be careful when modeling beams. If you use standard finite elements then the beam’s torsional stiffness could be overestimated, which could erroneously reduce the deflection in the adjacent slabs.

In RAM Concept , there is no difference between standard slab and beam elements, and standard elements have a torsional stiffness that is proportional to their depth cubed.

The actual torsional stiffness of a beam is proportional to the cube of the lesser value of depth and width. Standard elements thus overestimate the torsional stiffness of beams that are deeper than they are wide.

For this reason, you should consider using the "No-torsion" behavior for beams, especially deep edge beams. See "Beam properties" for more information.
