Does it make a difference if I model a floor-level downstand beam as a ‘Rib’ or as a ‘Result Beam’?


Yes, it makes because this affects the stiffness of the entire system.

When entering a level-floor downstand beam as a ‘Rib’, you will add the stiffness of the defined rectangular cross-section to the area of the line.

For the result beam, however, you have only to define the integration width. The entered rectangular cross-section does not influence the stiffness of the entire system but is only applied as a design cross-section in the add-on modules (e.g. RF-CONCRETE Members).
