AnswerIf you want to perform a buckling analysis with shell elements, the add-on modules RF‑STABILITY, RF‑IMP, and RF‑STEEL Surfaces are required.
Determining governing load according to the linear static analysis
The results of the governing CO are then used in RF‑STABILITY to determine the lowest mode shape (local deflection / buckling of surface).
With the result of RF‑STABILITY, you can generate a pre‑deformed structure in RF‑IMP by scaling the mode shape to a maximum ordinate (maximum value of the initial deformation). An engineer has to define the maximum value of the initial deformation.
Now, you can copy the governing CO and design this according to the second-order analysis while considering the pre-deformed structure of RF‑IMP.
The results are then used to perform the stress analysis in RF‑STEEL Surfaces.
The attached video shows the general procedure again.There are already some very interesting technical articles on this topic on our website.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
