Question
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?Answer
The cross-sections of members are always related to the centroidal axis in RFEM/RSTAB. The rendering is adjusted accordingly. This has no influence on the calculation.

Modeling Downstand Beams in Cross-Laminated Timber Constructions with Ribs
This time, we want to look at modeling downstand beams by means of ribs.
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.

- Is it possible to open the RX‑TIMBER files in RFEM and RSTAB?
- Which forces must be exchanged between the RX‑TIMBER Glued‑Laminated Beam program and the RX‑TIMBER Brace program?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
- After the design with RF‑/TIMBER Pro, I optimized a cross-section. Why is the utilization of the optimized cross-section exceeded now?
- Why are the stresses of the 90 ° orientation not displayed in RF-LAMINATE for a layer with the orthotropic direction 90 ° for σb, 90?
- How can I get the member end forces to design the connections?
- 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?
