Do you work with timber design? Then the Timber Design add-on is perfect for you! It allows you to perform cross-section resistance design and stability analysis of timber member and plate structures in the ultimate limit state. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.

Features
- A wide range of cross-sections, such as rectangular sections, square sections, T‑sections, circular sections, built-up cross-sections, irregular parametric cross-sections, and many others (suitability for design depends on the selected standard)
- Design of cross-laminated timber (CLT)
- Design of tapered and curved members (design method according to the standard)
- Adjustment of the essential design factors and standard parameters is possible
- Flexibility due to detailed setting options for basis and extent of calculations
- Fast and clear results output for an immediate overview of the result distribution after the design
- Detailed output of the design results and essential formulas (comprehensible and verifiable result path)
- Numerical results clearly arranged in tables and graphical display of the results in the model
- Integration of the output into the RFEM/RSTAB printout report

Cross-Section Resistance Features
- Design of tension, compression, bending, shear, torsion, and combined internal forces
- Consideration of a notch
- Support pressure design for internal and external supports
- Design of curved and tapered members
- Consideration of higher strengths for similar components that are close together (factor ksys according to EN 1995‑1‑1, 6.6(1)-(3))

Stability Analysis Features
- Stability analyses for flexural buckling, torsional buckling, and flexural-torsional buckling under compression
- Import of the effective lengths from the calculation using the Structure Stability add-on
- Graphical input and check of the defined nodal supports and effective lengths for a stability analysis
- Determination of the equivalent member lengths for tapered members
- Consideration of the lateral-torsional bracing position
- Lateral-torsional buckling analysis of the structural components subjected to moment loading
- Depending on the standard, a choice between user-defined input of Mcr, analytical method from the standard, and use of internal eigenvalue solver
- Consideration of a shear panel and a rotational restraint when using the eigenvalue solver
- Graphical display of a mode shape if the eigenvalue solver was used
- Stability analysis of structural components with the combined compression and bending stress, depending on the design standard
- Comprehensible calculation of all necessary coefficients, such as the factors for considering moment distribution or interaction factors
- Alternative consideration of all effects for the stability analysis when determining internal forces in RFEM/RSTAB (second-order analysis, imperfections, stiffness reduction, possibly in combination with the Torsional Warping (7 DOF) add-on)

Input
You can enter the structural system and calculate the internal forces in the programs RFEM and RSTAB. You have full access to the extensive material and cross-section libraries.
Timber Design is completely integrated into the main programs. At the same time, it automatically takes into account the structure and the available calculation results. You can assign further entries for the timber design, such as effective lengths, cross-section reductions, or design parameters, to the objects to be designed. You can easily select the elements graphically using the [Select] function at many places of the program.
5
Results
If your design is successful, the relaxed part of your work follows. Because the program does many processes for you. For example, the performed design chacks are displayed in a table. It shows you all the result details. Due to the clearly presented design formulas, you will be able to understand the results without any problems. There is no black-box effect here.
The design checks are carried out at all governing locations of the members and displayed graphically as a result diagram. Furthermore, detailed graphics, such as the stress distribution on a cross-section or the governing mode shape, are available for you in the result output.
All input and result data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual design checks.

Timber Member Compression Perpendicular to the Grain acc. to NDS 2018 and CSA O86:19
A standard scenario in timber member construction is the ability to connect smaller members by means of bearing on a larger girder member. Additionally, member end conditions may include a similar situation where the beam is bearing on a support type. In either scenario, the beam must be designed to consider the bearing capacity perpendicular to the grain according to the NDS 2018 (Sect. 3.10.2) and the CSA O86:19 (Clause 6.5.6 and 7.5.9). In the new generation RFEM 6 and Timber Design add-on, the added feature 'design supports' now allows users to comply with the NDS and CSA bearing perpendicular to the grain design checks.

How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- How can I efficiently define line hinges on several surfaces?
- Why cannot I define a rotation when defining layers?
-
How do I create an imperfection based on a mode shape in RFEM 6?
- Why does the load wizard "Member Load from Area Load" give unnecessary concentrated loads?

Special Solutions
First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
