Design with RFEM and RSTAB According to Swiss Standards
SIA Standards
The following SIA standards are implemented in the structural analysis programs by Dlubal Software:
Implemented Swiss Standards
1
Automatic Generation of Combinations in RFEM and RSTAB
Safety is also the top priority for your buildings in Switzerland. Using RFEM 6 / RSTAB 9, you can create load and result combinations automatically according to the Swiss standards SIA 260 and SIA 260 | Timber.
2
Timber Design According to SIA 265
If you are planning timber structures conforming the design standards, you have come to the right place. In the Timber Design add-on for RFEM 6 / RSTAB 9, you can find all the typical ultimate limit state, stability, serviceability liit state, and fire resistance design checks of timber members according to the Swiss standard SIA 265.
3
Seismic Design According to SIA 261
The Modal Analysis add-on for RFEM 6 / RSTAB 9 supports you when determining natural frequencies and mode shapes.
Another useful program is the Response Spectrum Analysis add-on for RFEM 6 / RSTAB 9. Here, you can perform seismic analyses using the multi-modal response spectrum analysis. Among others, you can find the Swiss standard SIA 261 implemented in the add-on.
4
Design of Reinforced Concrete Members and Surfaces According to SIA 262
The module extension SIA 262 for RFEM 5 / RSTAB 8 provides you with some additional content. Thus, you extend various add-on modules for concrete design by the Swiss standard SIA 262.
5
Steel Design According to SIA 263
In the RF‑/STEEL SIA add-on module for RFEM 5 / RSTAB 8, you can perform the ultimate and serviceability limit state design of members and continuous members according to the Swiss standard SIA 263.

Frequently Asked Questions (FAQ)Customer Projects
Fascinating customer projects designed with the Dlubal structural analysis software.
Considering Elastic Slip Modulus of Timber Connection
For a timber connection as shown in Figure 01, you can take into account the torsional spring rigidity (spring stiffness for rotation) of the connections. You can determine it by means of the slip modulus of the fastener and the polar moment of inertia of the connection.
- When performing the fire resistance design with TIMBER Pro, I get Error 10001. How can I fix the error?
- Is it also possible to reduce the shear force on a support or perform design with the shear force at a distance d to the support in RF‑CONCRETE Surfaces?
- When performing "manual definition of the reinforcement areas" in RF‑CONCRETE Surfaces, do I have to completely reinforce the entire structural component manually? Or does RF‑CONCRETE Surfaces apply the required reinforcement in the areas where I have not performed the manual definition?
- When I create a user-defined result value, the RFEM solver window opens briefly and the calculation is apparently performed again. Why? I have already performed the calculation.
- How can I consider loads from the self-weight as "favorable" and "unfavorable" for the combinations?
- For design with CONCRETE NL, is the creep applied to the entire cross-section, or only to the concrete compression zone?
- For a specific combination expression, I would like to consider a load case with a combination coefficient that deviates from the standard. How can I proceed?
- Is the compression reinforcement calculated for the ultimate limit state design in RF‑CONCRETE Surfaces? Or is it only possible in RF‑CONCRETE Members?
- I am designing a combined structure made of timber materials with different creeping parameters. How can I perform the serviceability limit state design according to EN 1995‑1‑1?
- In the RF‑/DYNAM Pro - Equivalent Loads add-on module, it is possible to consider accidental torsional actions. Which calculation approach is behind the calculation? Which values have to be entered for the eccentricities eX and eY?

RFEM 6
Main Program
The structural analysis program RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program can also design combined structures as well as solid and contact elements.

RSTAB 9
Main Program
The structural frame & truss analysis and design program RSTAB 9 contains a similar range of functions as the FEA software RFEM, paying special attention to frames and trusses. Therefore, it is very easy to use and for many years, it has been the best choice for the structural analysis of beam structures consisting of steel, concrete, timber, aluminum, and other materials.

Dynamic Analysis
In the Response Spectrum Analysis add-on, seismic analysis is performed using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from this. The add-on includes an extensive library of accelerograms from seismic zones. These can be used to generate response spectra.
