RSTAB - Structural Frame Analysis Program
Structural Engineering Analysis & Design Software
The 3D structural frame analysis program RSTAB is the ideal tool for the design of beam, frame, or truss structures consisting of steel, reinforced concrete, timber, aluminum, or other materials.
With RSTAB you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. For further design, there are various add‑on modules available, considering structural data of specific materials and standards.
Result Evaluation and Printout Report
Internal forces, deformations, and support forces are displayed in result tables and graphically on a model. Filtering options allow for targeted result selection. All data is documented in a multilingual printout report. The report contents can be adjusted and saved as a template.
Result tables display the available positive and negative internal forces in colors, including the relation to extreme values. The result tables of the design modules use color scales to represent respective design ratios. In this way, the governing locations are immediately apparent.
The result diagrams of members and set of members are freely configurable. You can define smooth ranges with average values or, if necessary, display or hide the results. This option ensures targeted evaluation of results. All diagrams can be added in the printout report.
The results on a rendered model are represented by a number of colors in order to easily detect deformations such as member rotation. You can freely define the colors and the range of values in the control panel. Deformation diagrams can be animated and saved as a video file.
The first result table displays a summarized overview providing the equilibrium of forces in the structural system and the maximum deformations. Information about the calculation process is included as well. You can filter the result tables by specific criteria such as extreme values or design locations.
It is possible to print a model, loads, and results in a series. Graphics can be created on the basis of different directions to be specified. For example, you can print all internal forces as an isometric view with a single mouse‑click.
There are various languages available for the results included in a printout report: English, German, French, Spanish, Italian, Czech, Slovak, Hungarian, Polish, Dutch, Portuguese, Russian, and Chinese.
You can individually create further language versions.
It is possible to import additional texts as RTF files. Page numbering can be configured as well in order to use prefixes, for example. Furthermore, you can export the printout report as a RTF or PDF file as well as in VCmaster.
The extent of a printout report can be individually adjusted by means of selection criteria. You can create printout templates based on already existing printouts and reuse them globally for all design projects. In the case of graphical print presentations, there is the option of title boxes.

Frequently Asked Questions (FAQ)
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Is it possible to renumber cross-sections and materials in RFEM and RSTAB?
- For a tapered member, I get the error message "Invalid (incompatible) arrangement ...". What can I do?
- As part of my bachelor thesis, I would like to integrate the RSTAB printout report into LaTeX. There, you can completely integrate a PDF document as shown in the viewer. This also works with any PDF document, but not with the printout report created by RSTAB. What could be the reason?
- I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- How can I set the deformation coefficient kdef in the program?
- How is the load distributed to the members in the angular axis method if the members are excluded from the load application?
- A rigid member should only be able to absorb tensile forces or only compressive forces. What are the options for considering these nonlinearities in the calculation?
- The installation of a Dlubal Software program is not possible due to the following message: "Program unsafe, protection by Microsoft Defender SmartScreen." How can I install the program?
