Load application point for determination of critical lateral-torsional buckling load
Video
First Steps with RFEM
Description
In the video we show the definition of eccentric member loading and its effect on the critical load factor for lateral torsional buckling. A load applied at the compressed flange will have a destabilizing effect in this case which is correctly considered in RFEM. We use the RFEM 6 Add-Ons Stability Analysis and Torsional Warping (7DOF).

Evaluating and Documenting Steel Joints Analysis Results in RFEM 6
With the RFEM 6 add-on Steel Joints, you can analyze steel connections by using an FE model. This article demonstrates how to evaluate and document the steel joints analysis results.

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
