Effective Sections is an extension of RSECTION. It determines the effective sections according to the following standards:
-
EN 1993-1-5 - EN 1993-1-3
- EN 1999-1-1
1
Features
- Available for general thin-walled RSECTION cross-sections
- Classification according to
- EN 1993-1-1
- EN 1993-1-4
- EN 1999-1-1
- Determination of the effective section according to
- EN 1993-1-5
- EN 1999-1-1
- Consideration of the effects of distortional buckling of cold-formed sections via eigenvalue method
- Determination of the stresses on the effective section and gross section
- Cross-section design, stability analysis, and serviceability limit state design for
RSECTION cross-sections of Class 4 according to EN 1993‑1‑1 in the Steel Design add-on - Available for all National Annexes integrated in the Steel Design add-on

Input
Effective Sections is fully integrated in RSECTION, so all input options of RSECTION are available. In the base data, you only have to specify the standard group according to which the effective section is determined. After importing the section into the main program RFEM or RSTAB, it is available for design in the Steel Design add-on like a library section.

Results
The design results are displayed in the usual way in the Steel Design add-on. The corresponding output tables show, among other things, the classification, the effective section properties, and the design check. The stresses are displayed graphically on the effective section as well as on the gross section.

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
- Which cross-sections can I design with the "RF‑/STEEL Cold-Formed Sections" add-on module?
- Is it possible to model cold-formed sections in SHAPE‑THIN 8 and to design them in RF‑/STEEL Cold-Formed Sections?
-
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?
