Merging Identical Definitions of Materials and Cross-Sections

When modeling more complex structures with an increased degree of repetition, identical material and cross-section definitions often occur.

To optimize this situation retroactively, RFEM and RSTAB provide the shortcut menu function "Merge Identical Cross-Sections/Materials" in the material and cross-section tables.

Merge Identical Cross-Sections

This function compares the selected table entry to all other entries and merges identical table entries into one entry.

To open the context menu with this function, right‑click in the description column of the material or cross‑section table. If there is no corresponding identical entry for the selected cross‑section / material, the mentioned function appears dimmed.

This merging becomes important when assembling the calculation model from several components via the Windows clipboard. This is because when inserting the clipboard model data, new material and cross-section definitions are automatically created for the affected elements due to a missing connection. Thus, after inserting several components, duplicate definitions result, which can be combined again with the merge function.

Knowledge Base Articles

Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

Rolled sections, the most common cross‑section type in RFEM and RSTAB, can also have user‑defined parameters. To do this, select the cross‑section to be modified in the cross‑section library and click the [Parametric Input...] button.

In this article, the adequacy of a 2x4 dimension lumber subject to combined biaxial bending and axial compression is verified using the RF-/TIMBER AWC add-on module. The beam-column properties and loading are based on example E1.8 of AWC Structural Wood Design Examples 2015/2018.

The add-on modules for designing structural member components according to national, European, and international standards also show design results in addition to numerical output in tables graphically, as diagrams displayed on the framework.

Infotainment

Export RFEM or RSTAB Models to *.glb or *.glTF Format

RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). View the models in 3D in detail with a 3D viewer from Google or Babylon. Take your VR glasses, such as Oculus, to "walk" through the structure.

You can integrate the 3D glTF models into your own websites using JavaScript according to these instructions (as on the Dlubal website Models to Download).

Activation of Camera Flight Mode in RFEM

With the Camera Fly Mode view option, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.
