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. 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.

  2. Options for Modeling Bored Piles

    RFEM and RSTAB offer different options to model bored piles. One option is to display bored piles as single-valued supports or hinged columns. Another option is the realistic modeling while taking into account the soil by means of applying a member elastic foundation. The two following examples will describe it in detail. However, pile base resistance, skin friction and soil layers are not considered in this technical article.

  3. Figure 01 - Hinged Column

    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.
  4. Columns Subjected to Tensile Stress in RF-/JOINTS Steel - Column Base

    The product range of Dlubal Software contains various modules for design of steel and timber connections. The RF-/JOINTS Steel - Column Base add-on module allows you to analyse footings of hinged or restrained steel column bases. For the cost-effective and safe design of the column base, the fastener selection, foundation geometry, and material quality are crucial.

  5. Rigid Columns in RF-/JOINTS Steel - Column Base

    A structural analysis does not only determine and design internal forces and deformations. It also ensures that the forces and moments in a structure are generated in a reliable way and applied to the foundation. Dlubal Software provides a wide range of products for structural analysis and design of steel and timber connections. The RF-/JOINTS Steel - Column Base add-on module allows you to design footings of hinged and restrained column bases. The design can be performed for both column base plates with or without stiffeners.

  6. Soil Profile

    As of the program version x.06.1103, it is possible to enter a soil profile in RF‑/FOUNDATION Pro. This provides you the advantage to set several soil layers with different soil parameters above and under the foundation base. For entering the soil layers, there is a library with various soils that can also be extended with user‑defined soils. The user-defined soil profile is shown in an interactive information graphic. Any change, for example a soil thickness modification, is reflected in the graphic immediately.

  7. Adjusting Secondary Bucket Reinforcement

    In RF-/FOUNDATION Pro, there is the relevant reinforcement concept for each design of bucket reinforcement by default.

  8. Comparison of Different Soil Models Using RFEM

    A foundation is usually created in RFEM using the subgrade reaction modulus method. The reason for this is the relatively easy and straightforward manageability. Also, no iterative calculations are necessary and the computing time is relatively small. The subgrade reaction means that, for example, a foundation plate is loaded flat elastically.

  9. Graphical Schema of Required Bending Reinforcement

    As of the program version x.06.1103, various optimizations are available. The RF‑/FOUNDATION Pro add‑on module has also been subjected to further development.
