Timber Design Add-on
Product Feature
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)

Timber Member Compression Perpendicular to the Grain acc. to NDS 2018 and CSA O86:19
A standard scenario in timber member construction is the ability to connect smaller members by means of bearing on a larger girder member. Additionally, member end conditions may include a similar situation where the beam is bearing on a support type. In either scenario, the beam must be designed to consider the bearing capacity perpendicular to the grain according to the NDS 2018 (Sect. 3.10.2) and the CSA O86:19 (Clause 6.5.6 and 7.5.9). In the new generation RFEM 6 and Timber Design add-on, the added feature 'design supports' now allows users to comply with the NDS and CSA bearing perpendicular to the grain design checks.

Timber Design | Manual Adjustment of Reference Lengths and Segmentation by Direction
The reference lengths to be considered in the calculation of the deflection limit value and the segments to be checked can be defined independently of each other, depending on the direction. For this, design supports are defined at the intermediate nodes of a member and assigned to the respective direction for the deformation analysis. In the resulting segments, it is also possible to define a precamber for each direction and segment.

How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- Why the eHORA map of Austria gives different snow loads than your Geo-Zone tool?
- Why does the load wizard "Member Load from Area Load" give unnecessary concentrated loads?
