Dear Dlubal Support Team,

I hope this message finds you well.

I am currently evaluating RFEM for structural analysis and I would like to inquire about its capabilities regarding stability analysis for reinforced concrete (RC) structures under extreme flood conditions. Specifically:

  1. Can RFEM perform stability (buckling) analysis for RC structures under high lateral and hydrostatic loads, such as those experienced during severe flooding?
  2. Which modules or add-ons would you recommend to accurately model nonlinear RC behavior in such scenarios?
  3. Are there any tutorials, webinars, or documentation demonstrating this type of analysis?

Your guidance will be highly appreciated, as I aim to ensure the software meets the requirements for critical structural analysis under extreme loading conditions.

Thank you very much for your time and support. I look forward to your response.

Hello ibrahimbrc,

the following article on our website describes in detail how to perform a nonlinear analysis using the example of a column. You can apply the same approach to a wall in order to analyze its nonlinear behavior. The required add-ons are also explained in the article.

As far as I know, EN 1992 does not explicitly address buckling in the sense discussed here. However, the following webinar on the buckling of steel structures may still be helpful for understanding the general analysis approach.

If you have any questions, feel free to ask.
