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.

  1. RF-/STEEL | Features

    • General stress analysis
    • Automatic import of internal forces from RFEM/RSTAB
    • Complete graphical and numerical results of stresses and stress ratios integrated in RFEM/RSTAB
    • Various options to adjust graphical results for evaluation
    • Flexible design in multiple design cases
    • Clearly arranged result tables for quick overview available immediately after design
    • High efficiency due to the minimum of data required for input
    • Flexibility due to detailed settings of parameters and extent of calculation
  2. Cross-Section Optimization

    Features of RF-/STEEL Members

    • Cross-section optimization
    • Transfer of optimized cross-sections to RFEM/RSTAB
    • Design of any thin-walled cross-section from SHAPE-THIN
    • Representation of stress diagram on a cross-section
    • Determination of normal, shear, and equivalent stresses
    • Stress results of individual internal forces types
    • Detailed representation of stresses in all stress points
    • Determination of the maximum Δσ for each stress point (for fatigue design, for example)
    • Colored display of stresses and stress ratios facilitating quick overview of crucial or oversized zones
    • Parts list and quantity surveying
  3. Colored Results in RFEM Graphic - Surfaces

    Features of RF-STEEL Surfaces (Available in RFEM Only)

    • Determine principal and basic stresses, membrane and shear stresses as well as equivalent stresses and equivalent membrane stresses
    • Stress analysis for structural surfaces including simple or complex shapes
    • Equivalent stresses calculated according to different approaches:
      • Shape modification hypothesis (von Mises)
      • Maximum shear stress criterion (Tresca)
      • Maximum principal stress criterion (Rankine)
      • Principal strain criterion (Bach)
    • Optional optimization of surface thicknesses and data transfer to RFEM
    • Serviceability limit state design by checking surface displacements
    • Detailed results of individual stress components and ratios in tables and graphics
    • Filter function for surfaces, lines, and nodes in tables
    • Transversal shear stresses according to Mindlin, Kirchhoff or user-defined specifications
    • Parts list of designed surfaces
  4. Material Library

    RF-/STEEL | Input

    In order to facilitate the data input, there are surfaces, members, sets of members, materials, surface thicknesses, and cross-sections preset. It is possible to select the elements graphically using the [Select] function. The program provides access to the global material and cross-section libraries.

    Load cases, load combinations, and result combinations can be combined in various design cases.

    Combination of surface and member elements and separate designs allow you to model and analyze only the critical areas such as frame joints by surface elements. The other parts of the model can be designed by member analyses.

  5. Colored Results in RFEM Graphic - Members

    RF-/STEEL | Results

    After the calculation, the module displays the maximum stresses and stress ratios sorted by cross-section, member or surface, set of members, and x-location. In addition to the result values in tables, the corresponding cross-section graphic including stress points, stress diagrams, and values is displayed as well. The stress ratio can refer to any kind of stress type. The current location is highlighted in the RFEM/RSTAB model.

    In addition to the result evaluation in the module, it is possible to represent the stresses and stress ratios graphically in the RFEM/RSTAB work window. It is possible to individually adjust the colors and values.

    Result diagrams of a member or set of members facilitate targeted evaluation. Furthermore, you can open the respective dialog box of each design location to check the design-relevant cross-section properties and stress components of all stress points. It is possible to print the corresponding graphic including all design details.
