Question:
How can I model a timber panel wall with RFEM?
Answer:
For modeling columns, bottom ribs, top ribs, and so on, you can use members for timber panels covered on one side.
If the timber panel is covered on both sides, we recommend replacing the members with surfaces. The columns are hinged to the top and the bottom rib. Then, you can define the covering.
For timber surfaces, make sure that the orthotropic material model is used.
When defining supports, you can decide whether they should be linear or nonlinear.
The flexibility of the connection between the covering and the members can be set using line releases. The springs refer to a length of 1 meter (kN/m/m = kN/m²), which is why the displacement modulus of the fastener must be multiplied by the number of fasteners per linear meter.
In the video, you can see the exact procedure. It shows the results first, then the modeling.
