Question:
For a truss with the steel lower flange and timber diagonals, I would like to design the connection of the diagonals. Is this possible?

Answer:
Yes, this is possible with the RF‑/JOINTS Timber - Steel to Timber add-on module. You can design the connection of two diagonals if they are connected with steel plates and dowels, for example. For this, it is reasonable to use the "Main member only" joint type.

After selecting the node in the program, the connection is still marked as insufficiently defined due to the steel bottom flange.

You can now deactivate both steel members to perform the design for the connection of the two diagonals only.

This design is possible in the add-on module.

Do you have any questions?

KB 001848 | Timber Column Design as per the 2018 NDS Standard in RFEM 6

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.

Image 1: Specific Parameters of Nonlinear Elastic Soil Material Model

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.

KB 001825 | WebService & API for Analysis of Construction Stages

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.

Product Features

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.

Feature 002585 | Fire Resistance Design of Surfaces for EN 1995 and SIA 265

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.

Feature 002615 | Cross-Laminated Timber Manufacturer Library for USA, Canada, and Switzerland

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.

The Timber Design add-on for RFEM 6 / RSTAB 9 is multi-purpose and combines a large number of additional elements. [*S16332764*] Timber Design Add-on for RFEM 6
