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. Transfer of Reinforcement from RFEM/RSTAB (Top) to Revit (Bottom)

    Bar Reinforcement Export to Revit

    The reinforcement concept from RF-/CONCRETE Members can be exported to Revit. Rectangular and circular cross-sections are possible at the moment. The reinforcement bars can be modified afterwards in Revit.
  2. Export of Reinforcement RFEM - Revit

    Surface reinforcements defined in the RF-CONCRETE Substructures add-on module can be transferred to Revit as reinforcement objects via the direct interface. Surfaces, rectangles, polygons, and round reinforcement areas can optionally be selected in RF-CONCRETE Surfaces for this purpose. In addition to rebar reinforcement, it is also possible to transfer rebar reinforcement.

  4. RF-CONCRETE Members - 1.1 General Data

    Features of RF-CONCRETE Members

    • Determination of longitudinal, shear and torsional reinforcement
    • Representation of minimum and compression reinforcement
    • Determination of neutral axis depth, concrete and steel strains
    • Design of member cross-sections affected by bending on two axes
    • Design of tapered members
    • Determination of deformation in cracked sections (state II), for example according to EN 1992‑1‑1, 7.4.3
    • Consideration of tension stiffening
    • Consideration of creep and shrinkage
    • Itemization of reasons for failed design
    • Design details for all design locations for better traceability of reinforcement determination

    • Output of complete steel schedule
    • Fire resistance design according to the simplified method (zone method) in accordance with EN 1992‑1‑2 for rectangular and circular cross‑sections
    • Optional extension of the RF‑CONCRETE Members add‑on module with a nonlinear calculation of frameworks for the ultimate and the serviceability limit state. The extension allows for design of potentially unstable structural components by means of a nonlinear calculation, or a nonlinear deformation analysis of 3D frameworks. Find more information under the product description of the RF‑CONCRETE NL add‑on module.
  5. RF-CONCRETE Surfaces - 1.1 General Data

    Features of RF-CONCRETE Surfaces

    • Free definition of two or three reinforcement layers in the ultimate limit state
    • Vectorial representation of the main stress directions of internal forces allowing optimal orientation adjustment of the third reinforcement layer to the actions
    • Design alternatives to avoid compression or shear reinforcement
    • Design of surfaces as deep beams (theory of membranes)
    • Option to define basic reinforcements for top and bottom reinforcement layer
    • Definition of designed reinforcement for serviceability limit state design
    • Results output in grid points of any selected grid
    • Optional extension of the module with nonlinear deformation analysis. The calculation is performed in RF‑CONCRETE Deflect by reducing the stiffness according to the standard, or in RF‑CONCRETE NL by the general nonlinear calculation determining the stiffness reduction in an iterative process.
    • Design with design moments at column edges
    • Itemization of reasons for failed design
    • Design details of all design locations for better traceability of reinforcement determination 
    • Export of isolines for the longitudinal reinforcement in a DXF file for further use in CAD programs as a basis for reinforcement drawings
  6. Detailed settings for analysis in RF-CONCRETE Surfaces

    RF-CONCRETE | Input

    In order to facilitate the data input, there are surfaces, members, sets of members, materials, surface thicknesses, and cross-sections preset in RFEM. It is possible to select the elements graphically using the [Select] function. The program provides access to the global material and cross-section libraries. Load cases, load combinations, and result combinations can be combined in various design cases. You can enter all geometric and standard-specific reinforcement settings for the reinforced concrete design in a segmented window. The geometry entries in both RF‑CONCRETE modules differ from each other.

    • In the RF‑CONCRETE Members add‑on module, you can define for example the curtailment of rebars, the number of layers, the cutting ability of links, and the anchorage type. For the fire resistance design of reinforced concrete members, you have to define the fire resistance class, the fire‑related material properties as well as the cross‑section sides exposed to fire.
    • In the RF‑CONCRETE Surfaces add‑on module, it is necessary to specify for example the concrete cover, the reinforcement direction, the minimum and the maximum reinforcement, the basic reinforcement to be applied or the designed longitudinal reinforcement as well as the rebar diameter.

    Surfaces or members can be summarized in special "reinforcement groups", each defined by different design parameters. In this way, it is possible to efficiently calculate alternative designs with different boundary conditions or modified cross‑sections.

  7. RF-CONCRETE Surfaces - Graphical results output for complete structural model

    RF-CONCRETE | Results

    After the calculation, the module shows clearly arranged tables listing the required reinforcement and the results of the serviceability limit state design. In addition, all intermediate values are displayed as well.

    The results of RF‑CONCRETE Members are displayed as result diagrams of each member. The reinforcement concepts of the longitudinal and the shear reinforcement including sketches are documented in accordance with current practice. It is possible to edit the reinforcement proposal and to adjust for example the number of reinforcement bars and the anchorage. The modifications will be updated automatically. A concrete cross‑section including reinforcement can be visualized in a 3D rendering. In this way, the program provides an optimal documentation option to create reinforcement drawings including steel schedule.

    The result of RF‑CONCRETE Surfaces can be displayed graphically as isolines, isosurfaces, or numeric values. It is possible to sort the longitudinal reinforcement display by required reinforcement, required additional reinforcement, designed basic or additional reinforcement, and by designed total reinforcement. The isolines of the longitudinal reinforcement can be exported as a DXF file for further use in CAD programs as a basis for reinforcement drawings.
