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.

    Creating Parametric Cross-Section

    The stand-alone program SHAPE‑THIN determines characteristic values and stresses of any thin‑walled cross‑sections. Graphic tools and features allow for modelling complex cross‑section shapes. In addition to the graphical input, it is also possible to enter the data in tables. As an alternative, you can import a DXF file and use it as a basis for further modelling. Also, each cross‑section can be entered using the cross‑section library of Dlubal Software and combined as a part with the user-defined elements.

  • Optimized Design Display in RF-/STEEL EC3

    Optimized Design Display

    RF-/STEEL EC3 performs the classification, cross‑section designs, serviceability limit state designs and fire resistance designs of members. For each design, the program shows a result table with the relevant values and classification numbers including information regarding the respective standard clause. In order to easily identify the conjunction of various standards, there is a final design equation including all terms at the end of the table.

  • Internal Pressure of Pipe Members

    Internal Pressure of Pipe Members

    In addition to a bending, torsional, longitudinal and strain load, you can also define and analyse internal pressure of the members with circular hollow cross‑sections in RFEM and RSTAB. The following perimeter and axial stresses resulting from the internal pressure load are analyzed using the Barlow's formula and transferred to design modules in order to superimpose the remaining stresses due to internal forces.

  • Roundup Function

    Roundup Function

    In RFEM and RSTAB, you can use formulas to determine a numerical value. In addition to general mathematical operations, verification and max/min functions are also possible. A roundup function is not included. However, it can be mapped using the available functions:

  • Using Formula Editor with Reference to Line Grid Input

    Using Formula Editor with Reference to Line Grid Input

    In the Formula Editor, you can specify any parameters (lengths, force magnitudes, etc.) to control the load and geometry data for modeling purposes.

  • Parameterized Input with Access to Cells of Other Tables

    Parameterized Input with Access to Cells of Other Tables

    With the parameterized input it is possible to access also cells of other RFEM or RSTAB tables. In this way, you can, for example, combine a load parameter with a model data parameter. The reference is created by the $ symbol.
