Exporting and Importing Combination Schemes

In RFEM and RSTAB, you can define a user-defined combination scheme. This can be helpful if a desired combination scheme cannot be created from a standard. In such cases, you can export the created load cases to Excel, create the scheme there, then import them to RFEM or RSTAB.

Combination Scheme

In a combination scheme, you specify the load cases, load combinations, and result combinations to be created with the relevant key data and basic settings.

In addition to the number of load cases, load combinations, and result combinations, you define the factors and superposition type in a combination scheme.

The [Generate in Tables Defined Load Cases, Load Combinations, and Result Combinations] button transfers the current combination scheme to the model.

Creating Combinations

Generated Combinations

The user-defined combination schemes are stored in the KombinSchema.dat file, which is located in the master data folder C:\ProgramData\Dlubal\Global\General Data by default. If you copy this file to another computer, you can also use the combination schemes there.

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.
