Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

    • 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

    • 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. RF-/TIMBER SANS | 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 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. RF-/TIMBER SANS | Design

    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-torsional 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. RF-/TIMBER SANS | Results

    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. 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.

    Design ratio is represented with different colors in the RFEM/RSTAB model. In this way, you can quickly recognize critical or oversized areas of the cross-section. Furthermore, result diagrams displayed on the member or set of members ensure 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. In this way, a comprehensible and clearly arranged documentation is guaranteed. You can select the report contents and the extent of the results specifically for the individual designs.
