Good day Dlubal support team,

I am currently working with RFEM5 to create a 3D model for a steel bridge. Only the self-weight and temperature loads have been applied. When using the RF-Steel EC3 add-on module, the message appears that the capacity verification results are not valid (see image).

However, when I display the graph with the utilization ratios, values are shown for all members (see image).

Therefore, I wanted to ask you whether I can use the values for my bridge assessment despite this message or if they are invalid. If I cannot use these utilizations, do you have any suggestions on how I can resolve this issue?

Thank you very much in advance for your support.

Hi n.marquardt,

thank you for your question.

To me the explanation actually is written in the text. It says that no Stability Analysis is done cause of Torsion in the section. Further explanations can be found on our homepage e.g. here.
