Hello,
I am modelling a beam-column system supporting beam panels in RFEM 6. The rest of the model is also defined using beam panels and I did not observe unexpected behavior elsewhere.
However, in this area the results suggest that the loads from the beam panels are being shared between the panel beams and the main beams of the beam-column system, and part of the load appears to transfer directly to the columns instead of passing through the beams. In addition, there is a region where it appears that no load from the beam panel is transferred to the main beams or to the columns.
The main beams were modelled along the lines defining the global surfaces of the beam panels.
Is there any specific modelling recommendation in RFEM 6 to ensure that the loads from the beam panels transfer first to the panel beams and then to the main beams before reaching the columns?
I am attaching screenshots of the model and the internal force diagrams for reference.
Please note that I am performing this check only for self-weight.
Thank you.
Hello Mariana,
by default, all linked objects behave like rigidly connected components.
To define that certain forces should not be transmitted, you can define joints or releases.
Alternatively, you can model with a minimal offset, for example "1mm gap" in between. This then really is a clean separation of the components.
Hello, Richard.
Thank you for your previous response and suggestions. Applying the line releases or introducing a small offset (about 1 mm) between the surface and the beam members helped resolve the issue in that area, and the post-beam system now behaves as expected.
However, I encountered a similar situation when introducing a vertical beam panel underneath/next to the beam panels/columns. In this case, neither the line releases nor the 1 mm offset seem to resolve the issue.
Could you please advise what would be the recommended modelling approach in this situation to ensure the correct load transfer?
Thank you again for your help.
Best regards,
Mariana
Hi Mariana, the beam panels are not prepared yet for wall-floor or wall-corner connections. Please create the beam panel inside the beam-column system and connect them if wished with ridig links:
