Effective Lengths for Lateral-Torsional Buckling
In RF‑/TIMBER Pro, it is also possible to define effective length for lateral-torsional buckling. The effective length for lateral-torsional buckling is then calculated according to EN 1995‑1‑1, Table 6.1. This option is useful especially for nonuniform load introduction.

In the add-on modules RF-/TIMBER Pro, RF-/TIMBER AWC, and RF-/TIMBER CSA, it is possible to consider the resulting deformation of a member or set of members. In addition to the local directions y and z, you also have the option ‘R’. This allows you to compare the total deflection of a girder to the limit values given in the standards.

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.
- How can I perform a stability analysis for a tapered member?
- Can I use RFEM to calculate a log house three-dimensionally?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- I would like to carry out the flexural buckling design for timber components with imperfections and internal forces according to the second-order analysis. Is it sufficient to activate this in Details of the RF‑/TIMBER Pro add-on module or is it necessary to make additional settings?
- Can I design laminated veneer lumber with RFEM/RSTAB?
- How can I calculate a timber-concrete composite floor with cross-laminated timber?
