The RF-/LIMITS add-on module allows you to compare the ultimate limit state of members, member ends, nodes, nodal supports, and surfaces (RFEM only) by means of a defined ultimate load capacity. Furthermore, you can check nodal displacements and cross-section dimensions.
Using this model, it was possible to compare the column bases with the maximum allowable forces specified by the manufacturer.

With the LIMITS module, you can compare the ultimate limit state of members, member ends, nodes, nodal supports, and surfaces (RFEM only) on the basis of a defined ultimate limit state. Furthermore, nodal displacements as well as cross-section dimensions can be checked. In this example, the column bases of a carport are to be compared with the maximum allowable forces specified by the manufacturer.

Compared to the RF-/TIMBER Pro add-on module (RFEM 5/RSTAB 8), the following new features have been added to the Timber Design add-on for RFEM 6/RSTAB 9:
- In addition to Eurocode 5, other international standards are integrated (SIA 265, ANSI/AWC NDS, CSA 086, GB 50005)
- Design of compression perpendicular to grain (support pressure)
- Implementation of eigenvalue solver for determining the critical moment for lateral-torsional buckling (only EC 5)
- Definition of different effective lengths for design at normal temperature and fire resistance design
- Evaluation of stresses via unit stresses (FEA)
- Optimized stability analyses for tapered members
- Unification of the materials for all national annexes (only one "EN" standard is now available in the material library for a better overview)
- Display of cross-section weakenings directly in the rendering
- Output of the used design check formulas (including a reference to the used equation from the standard)
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- Can I use RFEM to calculate a log house three-dimensionally?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Can I design laminated veneer lumber with RFEM/RSTAB?
- I would like to carry out the flexural buckling design for timber components with imperfections and internal forces according to the second-order analysis. Is it sufficient to activate this in Details of the RF‑/TIMBER Pro add-on module or is it necessary to make additional settings?
- How can I calculate a timber-concrete composite floor with cross-laminated timber?
- Is it possible to save the structures of the manufacturer-specific cross-laminated timber plates in the RF‑LAMINATE add-on module?
- How is it possible to display the main support direction graphically in RF‑LAMINATE?
