Recommended Add-on Products for Timber Structures
Multilayer Surfaces such as CLT and Timber Frame Walls
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.

In this article, the design of a timber panel wall with the beam panel thickness type is performed.

This article provides a comprehensive overview of essential seismic analysis methods, explaining their principles and applications, as well as the scenarios in which they are most effective
Fire design according to Chapter 16 of the NDS [1] for wood members and surfaces is available in the Timber Design add-on. This article shows how the charring of wood and reduced cross-sectional dimensions can be accounted for in the fire design with an example from AWC Technical Report No. 10 [2].
When calculating regular structures, data input is often not complicated, but it is time-consuming. Save your valuable time with input automation. The task described in the present article is to consider the stories of a house as single construction stages. Data are entered using a C# program so that the user does not have to enter the elements of the individual floors manually.
In the material library of RFEM, you can find plywood materials according to the US and Canadian standards ANSI/APA PRG 510 Plywood (USA/CAN).
For the fire resistance design of timber surfaces, you can display a charring diagram depending on the time of fire exposure.
It is also possible to print this charring diagram into the printout report.
In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. Simply specify the surface geometry and the timber panel elements are automatically generated using an internal member-surface construct, including the element connection stiffness. The Beam Panel thickness type is defined using the Multilayer Surfaces add-on.
A "beam panel" provides you with the following advantages:
- Single-sided or double-sided sheathing
- Automatic calculation of a semi-rigid coupling between studs and sheathing
- Nailed sheathing connection
- Stapled sheathing connection
- User-defined sheathing connection
- Representation as a complete geometric 3D object (frame, studs, surface, etc.), including eccentricity and automatically calculated stiffness between elements
- Consider openings via surface cells
- Design of the individual structural elements utilizing the Timber Design add-on (full shear wall design planned for a future release)
- Other material options available (e.g., particle board, gypsum, or fiberboard sheathing with cold-formed steel sections)
Do I need to add a line hinge/line release for the CLT wall-to-floor connection in the Building Model add-on?
How can I add counteracting dead loads (0.9*D) in NBC load combinations?
How can I perform member design by case for different settings in the design configuration?
How can I exclude the dead load in NBC load combinations when performing a deflection check?
What is the conservatism factor for CLT in Timber Design?
How can the NDS and CSA O86 factors be manually adjusted for consideration in the Timber Design add-on?
