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. Settings in the Results Navigator for the RF-PUNCH-Pro Results

    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.

  2. 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.

  3. Option "Nonlinear Calculation" in Window "1.1 General Data" in RF-CONCRETE Members

    Exporting Spring Stiffnesses from RF-/FOUNDATION Pro and the Influence on Column Design

    With RF-FOUNDATION Pro, it is possible to determine settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.

  4. Soil Parameters

    Determination of Bearing Resistance with "Drained" and "Undrained" Soil Conditions

    The RF-/FOUNDATION Pro add‑on module designs single foundations (foundation plates, bucket and block foundations) for all support forces arising in the RFEM/RSTAB model. The geotechnical designs are performed according to EN 1997-1.
  5. Example Model

    Punching Shear Design with Definition of Perimeters

    With RF-PUNCH Pro, the punching shear design can be performed according to 6.4, EN 1992-1-1. In the following example, the design according to DIN EN 1992-1-1 will be presented first with automatic design of the inner and outer perimeters and then on the basis of the inner perimeters defined by the user on a simple example.

  6. Structural System with Loads

    Design of Foundation Rotation

    Using RF-/FOUNDATION Pro, it is possible to perform geotechnical design according to EN 1997‑1 [1] for single foundations. The following article explains the design of highly eccentric loading in the foundation core according to DIN EN 1997‑1, A 6.6.5 (see [3]).

  7. Activating Ground Water Level for Soil Profile

    Influence of Ground Water Level on Design in RF-/FOUNDATION Pro

    Using RF-/FOUNDATION Pro, it is possible to perform geotechnical design according to EN 1997‑1 [1] for single foundations. Subsequently, the program displays detailed information about the influence of the ground water level on the selected design according to EN 1997‑1.

  8. Selecting Method for Determining Load Increasing Factor β

    Determining Load Increasing Factor β with Sector Model

    The RF-PUNCH Pro add-on module allows you to perform punching shear designs according to EN 1992-1-1 [1]. In addition to the designs of single columns, it is also possible to analyse wall ends and wall corners in RF-PUNCH Pro.

    At this point, I would also like to reference a previous article about RF-PUNCH Pro, which explains how to determine punching load on wall ends and wall corners.

  9. Data for Determining Allowable Soil Pressure

    Determining Bearing Resistance According to EN 1997-1

    In addition to the reinforced concrete design according to EN 1992-1-1, RF-/FOUNDATION Pro allows you to perform geotechnical designs according to EN 1997-1.

    In RF-/FOUNDATION Pro, the design of the allowable soil pressure is performed as a ground failure resistance design. If you select CEN as National Annex, you have two options for defining the ground failure resistance. First, you can directly specify the allowable characteristic value of the soil pressure σRk. Second, there is also the option to analytically determine the bearing capacity according to [1], Annex D.
