Composite Timber Beams
Model to Download
In RFEM 5 and RSTAB 8, it is possible to consider the flexibility of the connections at composed timber sections in the individual layers. This is achieved by entering the reduction factor gamma determined using the ‘gamma method’, for example, according to EN 1995‑1‑1 (Annex B) or DIN 1052:2008 (8.6.2).
This is demonstrated by applying this model.

The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.
The design of structural components at risk of buckling or lateral-torsional buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is compared to the maximal allowable deflection.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads.
Design-relevant parameters such as the stability analysis type, member slendernesses, and limit deflections can be freely adjusted.

- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- How can I set the deformation coefficient kdef in the program?
- 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?
- Can I consider a shear force reduction with the RF‑/TIMBER Pro add-on module?
