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. Defining the Stress-Strain Curve of Steel Fiber Reinforced Concrete

    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.

  2. 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.

  3. 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.

  5. 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.

  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. Superposition of deformation components

    Shear deformations of framework structures in timber construction

    In the current literature, the formulas for the manual determination of internal forces and deformations are usually specified without considering the shear deformation. Especially in timber construction, the deformations resulting from shear force are often underestimated.

  8. RFEM model

    Timber Beam Design per the 2014 CSA Standard

    Using the RF-TIMBER CSA module, timber beam design is possible according to the CSA O86-14 standard. Accurately calculating timber member bending resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored bending moment resistance in the RFEM add-on module RF-TIMBER CSA using step-by-step analytical equations per the CSA O86-14 standard including the bending modification factors, factored bending moment resistance, and final design ratio.

  9. RFEM Model

    Timber Beam Design per the 2018 NDS Standard

    Using the RF-TIMBER AWC module, timber beam design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member bending capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling in RF-TIMBER AWC using step-by-step analytical equations per the NDS 2018 standard including the bending adjustment factors, adjusted bending design value, and final design ratio.

  10. Finding the Start Nodes of Lines via the COM Interface

    Methods for Selecting Elements via the COM Interface

    When editing elements via the COM interface, selecting elements is often a problem because it cannot be carried out visually via the work window. The selection can be particularly difficult for models that have been created via the program interface and are then to be modified using a separate program. Besides the exception, when the selection was made previously via RFEM, there are several alternatives for programming.
