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. 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. Properties and calculation of result values of line supports

    When evaluating line support forces, implausible diagrams sometimes arise at first glance. In particular, for variable loads at locations that also have a nodal support, at division points and edge locations of supported lines, the results show sometimes unexpected support reactions. Using the function of the linear smooth distribution in the Project Navigator - Display does not always lead to the expected result diagram.

  3. 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.

  4. 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. Comparison of Results

    Effect of Different Ways to Model Line Supports in Glass Structures

    Due to the special properties of glass, you also have to pay close attention to detail points when modeling in an FE model. Glass has a very high compressive strength and is therefore generally only designed for its tensile stresses. A particular disadvantage of the material is its brittleness. Stress peaks that occur in the calculation must therefore not be readily neglected.

  6. Required Reinforcement for the Rib and Axial Force Distribution of the Wall

    Modeling and Determining Internal Forces for a T-Beam with Masonry Wall Above

    When modeling a reinforced concrete rib with a masonry wall above, there is the risk that the rib is underdesigned if the structural behavior of the masonry is not correctly considered and the connection between masonry wall and downstand beam is not modeled sufficiently accurate. This article deals with this issue and shows possible modeling options of such a structure. In this example, the reinforcement is determined only from the internal forces and without any secondary minimum reinforcement.

    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.

  9. 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.

  10. 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.
