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. Simulation of a stiffening pane in RSTAB

    The modeling of planar structural components such as glass panes is generally only possible in RFEM. If it is necessary to define the stiffening effect of a pane in a particular case, it can also be simulated in RSTAB.

  2. Calculation of timber panel walls

    This article shows the effect of the different stiffnesses of the timber panel walls on the floor plan.

  3. 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.

  4. Fire resistance analysis by means of a parametric temperature-time curve according to DIN EN 1991-1-2

    With RF-/STEEL EC3, nominal temperature-time curves can be used in RFEM or 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.

  5. Creation of a user-defined antenna support for RF-/TOWER attachments

    In the following, the creation of a user-defined antenna support for use in RF-/MAST extensions is described in detail.

  6. Determining the Material Properties of Steel Fiber Reinforced Concrete and Using in RFEM

    Steel fiber reinforced concrete is nowadays mainly used for industrial floors or hall floors, for foundation plates with low loads, basement walls and basement floors. Since the publication of the first guideline by the German Committee for Reinforced Concrete (DAfStb) about steel fiber reinforced concrete in 2010, the structural engineer can use standards for the design of the composite material steel fiber reinforced concrete, which makes the use of fiber reinforced concrete increasingly popular in construction. This article explains the individual material parameters of the steel fiber reinforced concrete and how to deal with these material parameters in the FEM program RFEM.

  7. 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.

  8. Maximum vertical deformation Crane runway beam with rigid supports

    Method for determining the allowable deformation of crane girders

    This article describes the different options for determining the allowable deformation of crane girders. Since multi-span beams and flexible lateral supports (curling bracing) are used in practice, clarity is to be created here about the selection of the correct method.

  9. Load Distribution on the Surface for the Governing CO

    Surface Load Inside the Critical Perimeter in RF-PUNCH Pro

    RF-PUNCH Pro performs the punching shear design on concentrated load application locations (column connection, nodal support and nodal load) as well as on wall ends and wall corners.

  10. System overview

    Determination of snow bag for height changes on roofs according to EN 1991-1-3

    Annexes are often found on buildings. If the roof levels are not at the same depth, this elevation jump (if more than 0.5 m) must additionally be considered for the snow load assumption.
