Does the RF‑LAMINATE program consider the shear correction factor for cross-laminated timber plates?
Answer
The shear correction factor is considered in the RF‑LAMINATE add-on module by using the following equation.
Layer | z_min | z_max | E_x(z)(N/mm²) | G_xz(z)(N/mm²) |
1 | -50 | -30 | 11,000 | 690 |
2 | -30 | -10 | 300 | 50 |
3 | -10 | 10 | 11,000 | 690 |
4 | 10 | 30 | 300 | 50 |
5 | 30 | 50 | 11,000 | 690 |
χ1 | 13.75 106 |
χ2 | 8.935 106 |
χ3 | 9.47 106 |
χ4 | 8.935 106 |
χ5 | 13.75 106 |
$\sum_{i=1}^n\frac1{G_{i;yz}}\left(χ_i^2(z_{i,max}-z_{i,min})-χ_iE_{i,y}\frac{z_{i,max}^3-z_{i,min}^3}3+{E^2}_{i,y}\frac{z_{i,max}^5-z_{i,min}^5}{20}\right)=$

Considering the Joint Slip in Parametric Timber Cross-Sections
In timber design, beams are often built up of several timber elements. The individual elements can be connected by 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.Screenshots

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
Frequently Asked Questions (FAQ)
- Can I design laminated veneer lumber with RFEM/RSTAB?
- Is it possible to perform a detailed analysis of connections, supports, or reinforcements of cross‑laminated timber plates in RF‑LAMINATE?
- How are the signs to be interpreted for the release results of the line release and line hinges?
- How can I create a curved or curved section?
- After the design with RF-/TIMBER Pro, I had a cross-section optimized. Why is the utilization of the optimized cross -section now exceeded?
- Is it possible to design the support pressure or the sleeper pressure in RX-TIMBER?
- 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?
- How can I run the RX‑TIMBER Frame plugin? I did not find it in the Add-on Modules menu nor in Project Navigator - Data.
