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. Natural Fire Scenario

    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.

  2. Streamline Diagram

    Wind Load on Rectangular, Rounded Structural Components

    The wind load of rectangularly rounded structural components is a complex matter. The equivalent forces from wind load depend on the strength of the circulating wind load and the component geometry.

  3. Structure

    Determining the Snow Accumulation for Height Differences on Roofs According to EN 1991-1-3

    Buildings often have extensions. If the roof levels are not at the same height, this height difference (if more than 0.5 m) must additionally be considered for the snow load assumption.

  4. Structure and Wind Load Due to Friction

    Wind Force Due to Friction

    The wind, which blows parallel to the surfaces of a structure, can generate friction forces on these surfaces. This effect is mainly important for very large structures.

  5. Flanged Guide

    Horizontal Craneway Loads from Skewing of Bridge Cranes

    For crane runways with large spans, the horizontal load from skewing is often relevant for the design. This article describes the origin of these forces and the correct input in CRANEWAY. The practical implementation and the theoretical background are discussed.

  6. Graded Wind Load Over Different Building Heights

    Wind Depending on the Structure Height for Vertical Walls

    The wind loads are regulated according to Eurocode 1 - Actions on structures - part 1-4: General actions - Wind loads. The nationally determined parameters of a respective country can be found in the National Annexes.

  7. Wind Zones of Germany

    Wind Load on Monopitch and Duopitch Roofs in Germany

    In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m.
  8. Classification of Surfaces Total Pressure Coefficients

    Determination of Wind Loads for Canopy Roof Structures According to EN 1991-1-4

    If a canopy roof, for example a filling station roof, should be designed, a load determination having regard to Section 7.3 of EN 1991-1-4 is required. This article shows with an example the design of a slightly inclined troughed roof.
  9. Snow Load Zones of Germany

    Snow Load on Monopitch and Duopitch Roofs

    In Germany, DIN EN 1991-1-3 with the National Annex DIN EN 1991-1-3/NA regulates the snow loads. The standard applies to civil engineering works at an altitude of up to 1,500 m above sea level.
  10. Generating wind loads

    Consideration of the correlation with wind loads

    If the wind load for buildings or structures is to be determined by the simultaneous assumption of aerodynamic pressure and suction coefficients on the windward and leeward sides of the building, the correlation of the wind pressure on zones D and E of the wall surfaces may be taken into account.
