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 ultimate limit state verifications are not feasible (see image).

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

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

Thank you 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.
