AnswerFor the design using Equivalent Member Method and General Method, there are four degrees of freedom considered in the eigenvalue solver. These are as follows:
If the RF‑/STEEL Warping Torsion add-on module is activated, there are seven degrees of freedom available:
- uY' (displacement from the plane)
- φX' (rotation about the X'-axis)
- φZ' (rotation about the Z'-axis)
- ω (warping)
- ux (displacement in x)
- uy (displacement in y)
- uz (displacement in z)
- φx (rotation about the x-axis)
- φy (rotation about the y-axis)
- φz (rotation about the z-axis)
- ω (warping)
AnswerYou can change the cross-section, generally adjust the model and its loads, or activate stabilization measures in STEEL EC3.The settings of rotational restraint and shear panel defined in window 1.12 Parameters - Members or 1.13 Parameters - Sets of Members, which are then considered in the module-internal eigenvalue solver to determine the critical load, are particularly suitable for this.
To display the mode shape, the calculation must be successfully performed. If this is not possible, there are either invalid boundary conditions or no stability problem was found (convergence not reached). No critical buckling shape can be considered then.

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. ”
