First Steps with RFEM
Description
The previous article, Lateral Torsional Buckling in Timber Structures | Examples 1, explains the practical application for the determination of the critical bending moment Mcrit or the critical bending stress σcrit for the lateral buckling of a bending beam by using simple examples. In this article, the critical bending moment is determined taking into account an elastic foundation resulting from a stiffening bracing.

Lateral-Torsional Buckling in Timber Construction | Examples 2
The previous article Lateral-Torsional Buckling in Timber Construction | Examples 1 explains the practical application for determining the critical bending moment Mcrit or the critical bending stress σcrit for a bending beam's lateral buckling by using simple examples.
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 are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched 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.
- I have a question about the results of the serviceability limit state design: How is the increment of the dead load by the factor 1.8 and the imposed load by 1.48 explained in the result combinations for the SLS design?
- Where can I adjust the effective length lef according to Table 6.1 of Eurocode 5 in the TIMBER Pro add-on module?
