Question
How is it possible to consider edge lamellas of a glued-laminated beam?Answer
In the main program RFEM/RSTAB, a member rotation of 90 ° is required so that the lamellas of the glued-laminated timber beam lie on edge, see Figure 01.
To ensure that the upright position of the beam is also taken into account in the design in the RF-/TIMBER Pro add-on module, you have to activate the increased strength for upright bending stress within the parameters of the National Annex in the "Other Settings 2/2" tab, see Figure 02.

Calculating Timber Panel Walls | 2. Stiffness and Slip of a Wall
The calculation of timber panels is carried out on simplified member or surface structures.

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).
