I dimensioned a steel construction connection with the add-on module RF-JOINTS and modeled it for comparison in RFEM. Why are the results not identical?

Answer

Please note that in RF-JOINTS there is an idealized verification of a steel construction connection according to the standard and this can not be easily compared with an exact FE mesh calculation.

Accordingly, for example, the following conditions must be observed:

  • Consideration or exclusion of friction / pressure / tension within the contact volume (register "Contact"), as well as with the modeled screws.
  • Consideration of internal forces and deformations within post-modeled end plates or the like, due to which a rearrangement of the screw forces takes place in the FE calculation - in contrast to the idealized proof in RF-JOINTS. Remedy can be created for example by rigid connection objects (for example, face plate as a rigid surface).
  • Uniform load transfer into the FE model, for example with the help of rigid bars / rigid surfaces, as in the article FEM modeling approach for rigid connections .
