Multilayer Surfaces (e.g. Laminate, CLT) for RFEM 6
Add-On
The "Multilayer Surfaces" add-on for RFEM 6 optimizes the modeling and analysis of multilayer timber structures, ideal for cross-laminated timber and timber stud walls. It effectively supports the structural analysis of prefabricated timber panels.
Hybrid Timber Construction with Complementary Materials
Building Model for RFEM 6
Add-On
The "Building Model" add-on simplifies the modeling and analysis of timber buildings. It speeds up the creation of building models and automatizes the load generation, ideal for demanding structural timber projects.
Construction Stages
Construction Stages Analysis (CSA) for RFEM 6
Add-On
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Optimization of Model Parameters
Optimization & Cost / CO2 Emission Estimation for RFEM 6
Add-On
The add-on uses particle swarm optimization (PSO) to determine optimal parameters for parameterized models based on weight, cost, or CO2 emissions.
Response Spectrum Analysis
Response Spectrum Analysis for RFEM 6
Add-On
The Response Spectrum Analysis add-on performs seismic analysis 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 them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.

Optimizing Projects with RFEM 6 by Dlubal Software: Investment Without Hesitation
After researching the with structural analysis software market, I finally decided to choose RFEM by Dlubal for the design of all types of timber structures (traditional framework, glued-laminated timber, timber-framed walls, mechanically welded fittings, and so on). The software is quite easy to learn and relatively intuitive; I don't need any training.
If you get stuck on a topic, you can rely on fast and efficient support. Moreover, there is multi-material software that can solve all the issues you encounter.
In other words, go ahead and invest!

RFEM 6 by Dlubal: Best Choice for 3D Timber Design According to Swiss SIA Standards
After analyzing the other structural analysis software offers on the market, we chose Dlubal's RFEM to calculate our three-dimensional timber structures.
This is the software that we believe is best suited for structural analysis and design according to the Swiss SIA standards.
The user interface is clear and intuitive, the results are displayed in detail, they can be edited and checked manually, which minimizes the effect of a "black box" and supports engineers in their decision-making.
The technical support team is attentive to our needs, reacting quickly and competently, responsive and competent, which confirms our choice.

This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
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.
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.
In RFEM 5 as well as RSTAB 8 in RF-/FOUNDATION Pro, you can save the foundation dimensions for all five foundation types as foundation templates in a user-defined database and use them later in other models.
Various design parameters of the cross-sections can be adjusted in the serviceability limit state configuration. The applied cross-section condition for the deformation and crack width analysis can be controlled there.
For this, the following settings can be activated:
- Crack state calculated from associated load
- Crack state determined as an envelope from all SLS design situations
- Cracked state of cross-section - independent of load
In the "Deflection and Design Support" tab under "Edit Member", the members can be clearly segmented using optimized input windows. Depending on the supports, the deformation limits for cantilever beams or single-span beams are used automatically.
By defining the design support in the corresponding direction at the member start, member end, and intermediate nodes, the program automatically recognizes the segments and segment lengths to which the allowable deformation is related. It also automatically detects whether it is a beam or a cantilever due to the defined design supports. The manual assignment, as in the previous versions (RFEM 5), is no longer necessary.
The "User-Defined Lengths" option allows you to modify the reference lengths in the table. The corresponding segment length is always used by default. If the reference length deviates from the segment length (for example, in the case of curved members), it can be adjusted.
This feature also contributes to the clearly-arranged display of your results. Clipping planes are intersecting planes that you can place freely throughout the model. The zone in front of or behind the plane is consequently hidden in the display. This way, you can clearly and simply show the results in an intersection or a solid, for example.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
Why do the min/max values of the total displacement not match the deformations when working with result combinations?
My model is unstable. What could be the reason?
I would like to enter a high spring constant. Is it possible?
Is it possible to switch off the minimum internal forces when displaying a result diagram so that only the maximum values are displayed?
I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I remove this cross-section from the selection quickly?
How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
