In the cross-section program RSECTION, you can generate parts in the corners when creating new elements.
In RFEM, you can generate surfaces from members with the library cross-sections as well as from the members with the RSECTION cross-section.

You can open the cross-sections in RSECTION using a direct connection, modify them there, and transfer them back to RFEM/RSTAB. Both RSECTION cross-sections and library cross-sections, with the exception of elliptical, semi-elliptical and virtual joists, can be opened and modified directly in RSECTION by clicking a button.
For example, you can thus adjust the reinforcement layout of user-defined RSECTION cross-sections directly in a local RSECTION environment in RFEM/RSTAB. This feature is currently only available for cross-sections with a uniform distribution type. The shear and longitudinal reinforcement defined for library cross-sections is not imported into RSECTION.
In the "Plastic capacity design | | Simplex method", RSECTION not only varies the normal stresses, but also the shear stresses over the cross-section area. This extended form of analysis allows you to use redistribution reserves, especially for the cross-sections subjected to shear loading, thus loading the cross-sections even more efficiently.
Go to Explanatory VideoYou can design any RSECTION cross-section in the Concrete Design add-on. Define the concrete cover, shear force, and longitudinal reinforcement directly in RSECTION.
After importing the reinforced RSECTION cross-section into RFEM 6 or RSTAB 9, you can use it for design in the Concrete Design add-on.
Go to Explanatory VideoWould you like to create a cross-section from the import of a DXF file? It's very easy. You have the following options:
- Create elements automatically
- Use DXF template lines as centerlines of elements with a defined thickness
Do you select the option to create the elements automatically? In that case, the program creates the elements and the associated parts for you from the contour of the outline. It only creates the elements not exceeding a definable maximum thickness.
Your cross-section geometry is available as a centroidal axis model? Then use DXF template lines as centerlines of elements with a defined thickness. Defining a thickness that is assigned equally to all elements.
Do you miss the "Create elements automatically" and "Create elements on lines" functions? Don't worry, both are also available in the "Edit" menu under "Manipulation".
When performing a design according to EN 1993‑1‑3, it is possible to graphically display a mode shape for the distortional buckling of a cross-section, and for the RSECTION cross-sections.
The mode shape can also be output in RSECTION 1 for library cross-sections.
It is possible to save different model versions within a model by using the Save as Version function. In the Base Data of the model, the different model versions can be displayed in the History tab.
The manual chapters are linked logically. After pressing the [F1] key, the program opens the corresponding chapter in the online manual.
Do you know about RSECTION 1 yet? The stand-alone program RSECTION helps you to determine the section properties for any thin-walled and massive cross-sections. Then, it performs a stress analysis. RSECTION combines the programs SHAPE‑THIN and SHAPE‑MASSIVE. Compared to these programs, we have added the following new features in RSECTION:
- Graphical display of stress components
- Scripting using Javascript

Effective Sections is an extension of the section properties program RSECTION. Compared to the RF‑/STEEL Cold-Formed Sections add-on module for RFEM 5 / RSTAB 8, the following new features have been added to Effective Sections:
- Consideration of the effects of distortional buckling of sections via eigenvalue method
- Definition of stiffeners and buckling panels no longer necessary
- Graphical display of unit stresses
- Optional manual definition of stress points
- 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 1993-1-3
- 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, stability, and serviceability limit state design checks for RSECTION cross-sections of Class 4 according to EN 1993‑1‑1 in the Steel Design add-on
- Cross-section checks for cold-formed RSECTION cross-sections according to EN 1993‑1‑3 in the Steel Design add-on
- Available for all National Annexes integrated in the Steel Design add-on
The Effective Sections extension is fully integrated in RSECTION. Therefore, all input options of RSECTION are available to you. You only need to specify the standard group in the Base Data, according to which the effective cross-section is to be determined. After importing the section into the main program RFEM or RSTAB, it is available for design in the Steel Design and Aluminum Design add-ons like a library section.
Are you just waiting for your results after the design? The design results are displayed in the usual way in the Steel Design add-on. In the corresponding output tables, you can find the classification, the effective section properties, and the design check, among other things. The stresses are displayed to you graphically on the effective section as well as on the gross section.

RSECTION contains an extensive library of rolled sections, as well as parametric thin-walled and massive cross-sections. You can compose them or supplement them with new elements.
Graphical tools and functions allow you to model complex section shapes in the usual way common for CAD programs. The graphical input supports, among other things, the setting of arcs, circles, ellipses, parabolas, and NURBS. As an alternative, you can import a DXF file and use this as the basis for further modeling. You can easily model a section consisting of different materials with minimum effort.
Furthermore, a parameterized input allows you to enter the cross-section dimensions and internal forces in such a way that they depend on certain variables.
You can also carry out all inputs by means of a script.
RSECTION calculates all relevant cross-section properties. This also includes the plastic limit internal forces. In the case of cross-sections consisting of different materials, RSECTION determines the ideal cross-section properties.
You have various options with RSECTION. For example, you can calculate the stresses from axial force, biaxial bending moments and shear forces, primary and secondary torsional moment, and warping bimoment for any cross-section shape. Determine the equivalent stresses according to the stress hypothesis by von Mises, Tresca, and Rankine.
RSECTION also offers everything you need in terms of overview. You can evaluate and visualize all results in an appealing numerical and graphical form. Selection functions support you in the targeted evaluation.
The printout report corresponds to the high standards of the FEA software RFEM and the frame analysis software RSTAB. Any modifications are updated automatically. You don't have to do anything.
