- Extensive library of permanent loads

- Determination of design ratios, support forces, and deformations
- Info icon indicating successful or failed design
- Color reference scales in result tables
- Direct data export to MS Excel
- DXF interface for preparation of production documents in CAD
- Program languages: English, German, Czech, Italian, Spanish, French, Portuguese, Polish, Chinese, Dutch and Russian
- Verifiable printout report including all required designs. Printout report available in many output languages, for example English, German, French, Italian, Spanish, Russian, Czech, Polish, Portuguese, Chinese or Dutch.
There are various options available for beam modeling. Graphical representations facilitate the geometry input. Modifications are updated automatically. Deflection of cantilevers can be set in the serviceability limit state design, independently from the deflection in the span.
The relevant timber grade of the material can be selected from the material library. All material grades specified in EN 1995-1-1: 2004 (EC 5) or DIN 1052:2008-12 and the selected National Annex are available for glulam, hardwood and softwood timber. Furthermore, it is possible to generate a strength class with user-defined material properties in order to extend the library. Permanent loads (for example roof structure) can also be entered using the comprehensive and extendable material library.
Generators integrated in RX-TIMBER Glued-Laminated Beam allow for comfortable generation of various wind and snow load cases. Load cases are displayed graphically and superimposed in automatically generated load combinations according to EN 1990, DIN 1055-100, or DIN 1052. In this way, the required input data is reduced to a minimum. However, you can enter load specifications manually as well.
In RX-TIMBER Glued-Laminated Beam, the following calculation settings are available:
- Designs to be performed:
- Selection of designs to be performed
- Determination of displaying support forces and deformations
- Adjusting the recommended limit values for the deformation analyses
- Definition of parameters for the fire resistance design performed according to the simplified method (optionally for F 30‑B, F 60‑B, F 90‑B, and user‑defined)
- Determination of tilting moment for pinned support
- Definition of support conditions for a beam
- Beam optimization by means of:
- Beam depth modification
- Modification of beam scene
- Cross-section width
- Spacing of lateral supports
After the calculation, the results of performed designs including all required intermediate values are displayed in clearly arranged result tables sorted by various criteria.
Since the program displays the intermediate values in detail, transparency of all designs is ensured. Furthermore, it is possible to display the distribution of internal forces for each x-location of the beam in a separate graphical window. Here, both the deformations and the individual internal forces can be displayed.
Designs with design details and selected result diagrams can be added in the printout report providing clearly arranged documentation. The printout report can include graphics, descriptions, drawings, and more. Moreover, it is possible to select which calculation data will be covered in the printout.

Compared to the RF‑/TIMBER Pro add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Timber Design add-on for RFEM 6 / RSTAB 9:
- In addition to Eurocode 5, other international standards are integrated (SIA 265, ANSI/AWC NDS, CSA 086, GB 50005)
- Design of compression perpendicular to grain (support pressure)
- Implementation of eigenvalue solver for determining the critical moment for lateral-torsional buckling (EC 5 only)
- Definition of different effective lengths for design at normal temperature and fire resistance design
- Evaluation of stresses via unit stresses (FEA)
- Optimized stability analyses for tapered members
- Unification of the materials for all national annexes (only one "EN" standard is now available in the material library for a better overview)
- Display of cross-section weakenings directly in the rendering
- Output of the used design check formulas (including a reference to the used equation from the standard)
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
- I have a question about the results of the serviceability limit state design: How is the increment of the dead load by the factor 1.8 and the imposed load by 1.48 explained in the result combinations for the SLS design?
- Which Dlubal Software programs can I use to calculate and design timber structures?
- Windows Defender does not allow me to install RX‑TIMBER. Is it possible to get around this?
- How can I perform a stability analysis for a tapered member?
- After opening a duopitch roof beam from RX‑TIMBER in RFEM/RSTAB, it is displayed with a gap in the apex zone. Does this affect the calculation?
- Which types of glued-laminated beams can be calculated with a raised dry joint?
- I have manually defined a snow load of 5 kN/m² in the RX‑TIMBER program. However, the calculation uses a load of 4 kN/m². Why is the defined snow load not applied?
- How do I create a user-defined material in the RX‑TIMBER program?
- How can I load the authorization file (AUTHOR.INI) in the RX‑TIMBER module?
