Description
Supports contributing to a load reduction only under compression or tension can be defined as nonlinear supports.
This model was used to explain the selection of the correct nonlinearity for "failure under tension" or "failure under compression."

Supports contributing to a load reduction only under compression or tension can be defined as nonlinear supports in RFEM and RSTAB. It is not always easy for the user to select the correct nonlinearity for "failure under tension" or "failure under compression".

Application of Connections to the Structure | Steel Joints
- The proposed connection can be applied to all selected nodes in the structure
- The location of the connection can be defined using the "Main" tab of the Add-on dialog box
- The design is performed for all connections in the structure and after the calculation, the results on all connections can be displayed
- The table shows the results for the individual connections, each connection is designed and can be saved separately

How do I set a release for warping?
- How can I define a warping spring or a warping restraint?
- At which point on a cross-section are the supports and loads assumed for the calculation with warping torsion?
- The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- How can I deactivate the 7th degree of freedom for certain members or cross-sections only?
