Design of Timber Members Acc. to South African Standards SANS 10163-1:2003 and SANS 10163-2:2001

The RF-/TIMBER SANS add‑on module can carry out designs of the ultimate limit state, serviceability limit state, and fire resistance according to the South African timber construction standard SANS 10163‑1:2003 and SANS 10163‑2:2001. It covers design methods according to:

  • Limit States Design (LSD)
  • Allowable Stress Design (ASD)

RF‑/TIMBER SANS includes a large cross‑section library as well as an extensive material library with standard‑specific strength values. In addition to stress designs, it is also possible to perform stability analysis for members in RF‑/TIMBER SANS according to the equivalent member method or the second order analysis. Furthermore, it is possible to perform the serviceability limit state and fire resistance designs.

  1. Features

    • Full integration in RFEM/RSTAB including import of all relevant information and internal forces
    • Design of members and sets of members in tension, compression, bending, shear and combined internal forces
    • Stability analysis for lateral torsional buckling and buckling according to the equivalent member method or the second order analysis
    • Serviceability limit state design in the form of deflection limits
    • Free setting of charring time and rates as well as free selection of charring sides for fire resistance design
    • South African material library and cross‑section library
    • User-defined entry of rectangular and circular cross‑sections
    • Optimization of cross‑sections with the possibility to transfer them to RFEM/RSTAB
    • Optional import of effective lengths from the RSBUCK or RF‑STABILITY add‑on module
    • Comprehensive result documentation with reference to used design equations from the standard
    • Wide range of options to filter and sort results including a list of designs by set of members, by cross‑section, by x‑location or by load cases, load or results combinations
    • Consideration of timber moisture conditions
    • Visualization of the design criterion on the RFEM/RSTAB model
    • Data export to MS Excel
  2. Window 1.1 General Data


    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 SANS. Material properties listed in the respective standard are included in the material library.

    When checking the cross‑sections, you can specify whether to consider the cross‑section selected in RFEM/RSTAB or a modified cross‑section in the design. After the cross‑section check, you can define the load duration classes (LDC), moisture conditions and timber protection.

    The deformation analysis requires the reference lengths of the relevant members and sets of members. Furthermore, you can define a specific direction of deflection, precamber and beam type.

    For fire resistance design, it is possible to define charring sides by member or set of members.

  3. Window 1.8 Effective Lengths - Sets of Members


    The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.

    The design of structural components at risk of buckling and lateral buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compression force as well as bending and tension. Deflection of inner spans and cantilevers is compared with the maximum allowable deflection.

    Separate design cases allow flexible analysis of the selected members, sets of members, and actions as well as for the individual stability analysis. Parameters relevant for design such as load duration in case of fire, member slendernesses, and limit deflection can be freely adjusted.

  4. Graphical representation of RF-/TIMBER SANS design results in RFEM


    After the calculation, the module displays results in clearly‑arranged result tables. All intermediate values (such as governing internal forces, modification factors, and others) are included, providing a transparent design process. The results are listed by load case, cross‑section, member, and set of members.

    If the calculation fails, you can modify the relevant cross‑sections in an optimization process. It is also possible to transfer modified cross‑sections from RFEM/RSTAB for a recalculation.

    Stress ratios are represented on the RFEM/RSTAB model by different colors in order to immediately recognize over-designed or critical areas of the model. Result diagrams of members and sets of members allow for a targeted evaluation.

    In addition to the input and result data in tables, you can add all graphics into the global printout report. In this way, coherent and clearly arranged documentation is ensured. The report contents and the extent of the results can be selected specifically for the individual designs.
