Composite Timber Beams
Model to Download
Description
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.

Considering the Joint Slip in Parametric Timber Cross-Sections
In timber design, beams are often built from several timber elements. The individual elements can be connected with glue, nails, bolts, or dowels. A glued connection is to be assumed as rigid. In the case of dowel‑type fasteners, the joint is compliant (slip joint), and the cross‑section properties of the connected elements cannot be fully applied.
