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. Structural System

    Calculating Timber Panel Walls | 2. Stiffness and Slip of a Wall

    The calculation of timber panels is carried out on simplified member or surface structures. This article describes how to determine the required stiffness.

  2. System Sketch

    Design of a welded connection of an I-section

    Design of a welded connection of a HEA cross-section under biaxial bending with axial force. Design of welds for the given internal forces according to the simplified method (DIN EN 1993-1-8, clause 4.5.3.3) by means of SHAPE-THIN.

  3. 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.

  4. Example:

    Smoothing of surface internal forces in RFEM

    When calculating a surface model, the internal forces are determined separately for each finite element. Since the element-by-element results usually represent a discontinuous distribution, RFEM performs a so-called smoothing of the internal forces that takes into account the influence of neighboring elements. In this method, the discontinuous distribution of internal forces is adjusted. The evaluation of the results is thus clearer and easier.

  5. Dialog Box 'Insert DXF Template'

    Cross-section modeling based on DXF files

    In SHAPE-THIN, you can import cross-section geometries that are available as outline or centroid layouts in DXF format and use them as a basis for modeling.

  6. 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.

  7. Effect of Different Modeling of Line Supports in Glass Structures

    Due to the special properties of the material glass, it is necessary to pay particular attention to detail points when modeling in an FE model. The glass has a very high compressive strength and is therefore tended to design only for its tensile stresses. A particular disadvantage of the material is its brittleness. Therefore, stress peaks occurring in the calculation must not be neglected without further ado.

  8. Structure, 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 acting on the strong axis is designed with the aid of the RF-/STEEL AISC add-on module according to EN 1993-1-1. Column head and column footing are assumed as lateral and torsional restraint. The column is not held against rotation between the supports. The cross-section of the column is a HEB 360 from S235.

  9. Definition of the stress-strain curve of the steel fiber concrete

    Determination of material properties of steel fiber reinforced concrete and its use in RFEM

    Steel-fiber reinforced concrete is nowadays mainly used for industrial floors or hall floors, low-stressed foundation plates, basement walls and basement floors. Since the publication of the first DAfStb guideline "Stahlfaserbeton" in 2010, the structural engineer has been implementing a set of rules and regulations for the design of the composite material steel fiber reinforced concrete, which makes the use of fiber reinforced concrete increasingly popular in construction practice. This article deals with the individual material parameters of the steel fiber concrete and the implementation of these material parameters in the FEM program RFEM.

  10. Reinforcement content in RFEM (top) and Revit (bottom) after export via direct interface

    Routes from BIM model to structural engineering and back

    The calculation of structures based on digital twins is increasingly becoming an everyday task in the engineering office. For if a digital building model already exists, you want to continue to use the information contained in it as seamlessly as possible. This places far-reaching requirements with regard to modeling and interfaces for BIM-compatible structural analysis software.
