RF-/TIMBER Pro designs timber members and sets of members on the basis of the design procedures according to:

  •  EN 1995‑1‑1 (including National Annexes; see below)
  •  SIA 265:2012 + SIA 265‑C1:2012
  •  DIN 1052:2008‑12

In addition to stress designs, RF‑/TIMBER Pro performs the stability analysis of members according to the equivalent member method or second‑order analysis as well as designs of the serviceability limit state and fire resistance. Furthermore, the module provides the option of automatic cross‑section optimization.

  2. Input

    After opening the add‑on module, it is necessary to select the members/sets of members, load cases, load or result combinations for the ultimate limit state, serviceability limit state, and fire resistance design. The materials from RFEM/RSTAB are preset and can be adjusted in RF-/TIMBER Pro. The material properties listed in the respective standard are included in the material library.

    After the cross-section check, the module determines the load duration classes (LDC) and the service classes (SECL). It is possible to assign them to the selected load cases and members.

    Combined cross-sections may consist of various materials. The RF-/TIMBER Pro add-on module performs designs considering the shifted neutral axis (in the case of semi-rigid cross-sections). The deformation analysis requires the reference lengths of the relevant members and sets of members. Furthermore, you can define a specific direction of deflection, a precamber, and the beam type.

  3. Design

    The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression, as well as shear due to shear force with and without torsion. Designs proceed at the level of design stress values.

    The design of structural components with a risk of buckling and lateral buckling according to the Equivalent Member Method and considers axial compression, bending with and without compressive force, and bending and tension. The deflection of inner spans and cantilevers is determined in characteristic and quasi-permanent design situations.

    Separate design cases allow for a flexible analysis of members, sets of members, and actions, as well as for the individual stability analyses. In the case of tapered members, the cut-to-grain angle is considered in the bending tension and bending compression area. If there is a ridge defined, the module performs the ridge design additionally.

  4. Results

    After the calculation, the module displays results in clearly arranged result tables. Each intermediate value is listed, making the designs transparent. The results are listed by load case, cross-section, member, and set of members.

    If the analysis fails, the relevant cross-sections can be modified in an optimization process. It is also possible to transfer the optimized cross-sections to RFEM/RSTAB to perform a new calculation.

    The design ratio is represented with different colors in the RFEM/RSTAB model. This way, you can quickly recognize critical or oversized areas of the cross-section. Result diagrams of members and sets of members enable targeted evaluation.

    In addition to the input and result data, including design details displayed in tables, you can add all graphics into the printout report. This way, comprehensible and clearly arranged documentation is guaranteed.
