  1. Member Type "Dashpot"

    The member type "Dashpot" can be used for time history analyses in RFEM with the add-on modules RF-DYNAM Pro - Forced Vibrations and RF-DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.

    With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model which consists of the damping element and an elastic spring (both connected in parallel).

  2. Data exchange with Advance Steel using *.smlx files

    When exchanging data with Advance Steel using *.smlx files, the interface is automatically detected. This means that *.smlx files are possible even if no version of Advance Steel is installed.

  3. Link to TeamViewer in Help menu of RFEM and RSTAB

    By opening the Help menu of RFEM and RSTAB, it is possible to directly access the TeamViewer. Customers with a Service Contract Pro can thus benefit from an easy and quick online support via video conference.

  4. RF-/JOINTS Timber - Timber to Timber | Features

    • Design of hinged connections
    • Biaxial inclination of the connected member (for example a jack rafter joint)
    • Connection of any number of members on one node for the “Main member only” type
    • Screw diameter of 6 mm – 12 mm
    • Automatic check of the minimum distance between screws
    • Optional free definition of screw distances
    • Transfer of eccentricity from RFEM/RSTAB
    • Crosswise or parallel screw alignment
    • Definition of up to 16 screws in a row
    • Graphical visualization of joints in the add-on module and in RFEM/RSTAB
    • Possibility to perform all required designs
  5. Window 1.1 General Data

    RF-/JOINTS Timber - Timber to Timber | Input

    First, it is necessary to select the joint type and the design standard.

    The connected members are imported from the RFEM/RSTAB model. The module automatically checks if all geometric conditions are fulfilled.

    Also the loads are imported automatically from RFEM/RSTAB. In the Geometry window, you can specify the screw parameters (diameter, length, angle, etc.).

  6. Parameters of National Annex

    RF-/JOINTS Timber - Timber to Timber | Design

    The following design results are displayed:

    • Check of the minimum spacing between screws
    • Load carrying capacity of each screw
  7. Results in Table

    RF-/JOINTS Timber - Timber to Timber | Results

    At first, the governing joint designs are arranged in groups and displayed with the basic geometry of the joint in the first result window. In the other result windows, you can see all fundamental design details.

    Dimensions and material properties important for the connection construction are displayed immediately and can be printed directly or exported to a DXF file. It is possible to visualize the connections in RF‑/JOINTS Timber - Timber to Timber or in the RFEM/RSTAB model.

    All graphics can be included in the RFEM/RSTAB printout report or printed directly. Result graphics to scale provide the option of an optimal visual check right from the design phase.

  8. RF-/DYNAM Pro - Nonlinear Time History | Features

    • User-defined time diagrams as a function of time, in a tabular form, or as harmonic loads
    • Combination of the time diagrams with RFEM/RSTAB load cases or combinations (enables definition of nodal, member and surface loads as well as free and generated loads varying over time)
    • Combination of several independent excitation functions
    • Nonlinear time history analysis with the implicit Newmark analysis (RFEM only) or the explicit analysis
    • Structural damping using Raleigh damping coefficients or Lehr's damping
    • Direct import of initial deformations from a load case or combination (RFEM only)
    • Stiffness modifications as initial conditions, for example axial force effect, deactivated members (RSTAB only)
    • Graphical display of results in a time course monitor
    • Export of results in user-defined time steps or as an envelope
  9. RF-/DYNAM Pro - Nonlinear Time History | Nonlinearities

    • Nonlinear member types, such as tension and compression members or cables
    • Member nonlinearities, such as failure, tearing, yielding under tension or compression
    • Support nonlinearities, such as failure, friction, diagram, and partial activity
    • Release nonlinearities, such as friction, partial activity, diagram, and fixed if positive or negative internal forces
  10. Time course monitor (temporary failure of tension member due to vibration stress)

    RF-/DYNAM Pro - Nonlinear Time History | Results

    Due to the integration of RF‑/DYNAM Pro in RFEM or RSTAB, you can incorporate numeric and graphic results from RF‑/DYNAM Pro - Forced Vibrations to the global printout report. Also, all RFEM and RSTAB options are available for a graphical visualization. The results of the time history analysis are displayed in a time course monitor.

    All results are plotted versus time. You can export the numeric values to MS Excel. It is possible to export the result combinations by exporting the results of the individual time steps or filtering the most unfavorable results of all time steps.
