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. Design of local load introduction according to EN 1993-1-3

    The design of cold-rolled steel products is governed by EN 1993-1-3. Typical shapes of cold-formed cross-sections are U, C, Z, Hut, or Sigma sections. They are produced from thin-walled sheet metal by roll-forming or edging methods. When designing the ultimate limit states, it is also necessary to ensure that local load application does not lead to compression, crippling of the web or local buckling in the web of the cross-sections. These effects can be caused by local load application through the flange into the web as well as by support forces at the supported points. Section 6.1.7 of EN 1993-1-3 specifies in detail how to determine the resistance of the web Rw, Rd under local load application.

  2. Design of a Thin-Walled, Cold-Formed C-Section According to EN 1993-1-3

    Utilize the RF-/STEEL Cold-Formed Sections module extension to perform ultimate limit state designs of cold-formed sections according to EN 1993-1-3 and EN 1993-1-5. In addition to the cold-formed cross-sections from the cross-section database, you can also design general cross-sections from SHAPE-THIN.

  3. Tilting a single-span beam

    Lateral-torsional buckling in timber construction: Theory

    Slender bending beams with a large h/b ratio and loaded parallel to the minor axis tend to have stability problems. This is due to the deflection of the compression chord.

  4. System

    Stability analysis of a column under normal force and bending

    In the following, a pendulum column with a centrally acting axial force and a line load acting on the strong axis will be determined by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-1.

  5. Calculation and Use of Laminated Glass

    Different glasses and layer structures are available for glass structures which are used for different purposes. The following types are usually used: float glass, partly tempered glass, and toughened safety glass.

  6. Assumptions for the Effective Tensile Strength Connected with Determining the Minimum Reinforcement According to DIN EN 1992-1-1 7.3.2

    When determining the minimum reinforcement for the serviceability limit state according to 7.3.2, the applied effective tensile strength fct,eff has a significant influence on the determined amount of reinforcement. The following article gives an overview about determining the effective tensile strength fct,eff and the input options in RF-CONCRETE.

  7. Punching Shear Design in RF-PUNCH Pro Taking Into Account Enlarged Column Head

    In RF-PUNCH Pro, enlarged column heads can be arranged at point-supported punching shear points, thus increasing the shear force resistance of a reinforced concrete floor. In the following article, we will show the punching shear design with the optional application of an enlarged column head.

  8. Fire Design With Parametric Temperature-Time Curve According to DIN EN 1991-1-2

    With RF-/STEEL EC3, you can utilize nominal temperature-time curves in RFEM and RSTAB. The standard time-temperature curve (ETK), the external fire curve and the hydrocarbon fire curve are implemented. Moreover, the program provides the option to directly specify the final temperature of steel.

  9. System, Loading, Internal Forces

    Cross-Section Design of a Column Under Axial Force and Bending

    In this technical article, a hinged column with a centrally acting axial force and a linear load that acts on the major axis is designed according to EN 1993-1-1 with the aid of the RF-/STEEL EC3 add-on module. Column head and column base are assumed as a lateral and torsional restraint. The column is not held against rotation between the supports. The cross-section of the column is an HEB 360 from S235.

  10. System Sketch

    Designing Welded Connection of I-Section

    A welded connection of a HEA cross-section under biaxial bending with axial force will be designed. The design of welds for the given internal forces according to the simplified method (DIN EN 1993-1-8, clause by means of SHAPE-THIN will be performed.
