Answer:
To define a dowel connection, the add-on module requires the minimum member length. This is 42 cm. If a member is shorter, the text "Member is too short" appears in Window "1.2 Nodes and Members" (see Image 01). However, the structural component is often broken by intermediate nodes, and consists of several members. In such cases, the structural component can remain as a member in RFEM and the nodes can be used with the "Create Node 'On Line'" feature (see Image 02). Thus, the member is not divided. All members connected to these nodes are then connected to each other, even if the member is not divided. As an alternative, it is possible to use the "Divide Member" feature with the "Place new nodes on the line without dividing it" option (see Image 03).
Question
There is a note in the RF‑/JOINTS Timber - Steel to Timber add-on module saying that the member length is too short. What is the minimum length, and how can I avoid the problem?

Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
The Geotechnical Analysis add-on provides RFEM with additional specific soil material models that are able to suitably represent complex soil material behavior. This technical article is an introduction to show how the stress-dependent stiffness of soil material models can be determined.
This article shows how to create cross-sections using DXF files.
When calculating regular structures, data input is often not complicated but time-consuming. Input automation can save valuable time. The task described in the present article is to consider the stories of a house as single construction stages. Data is entered using a C# program so that the user does not have to enter the elements of the individual floors manually.
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
- Sterling Structural
- Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
