First Steps with RFEM
Description
In the case of open cross-sections, the torsional load is removed mainly via secondary torsion, since the St. Venant torsional stiffness is low compared to the warping stiffness. Therefore, warping stiffeners in the cross-section are particularly interesting for the lateral-torsional buckling analysis, as they can significantly reduce the rotation. For this, end plates or welded stiffeners and sections are suitable.

- How can I enter a head plate at a frame joint for the stability analysis of a frame beam in STEEL EC3?
-
The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- How can I efficiently define line hinges on several surfaces?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
