  1. Adaptive Mesh Refinement

    Adaptive Mesh Refinement

    With this function, it is possible to refine the FE mesh on surfaces automatically. The mesh refinement is carried out step by step. In each step, a new FE mesh according to the numeric error analysis of the previous step will be generated. The numeric error will be evaluated by means of the results on surface elements and is based on the energy formulation by Zienkiewicz-Zhu.
    The error analysis is carried out for a linear static analysis. A load case (or a load combination) is selected for which the FE mesh will be generated. The FE mesh will be used for all calculations.
  2. Member Type "Dashpot"

    The member type "Dashpot" can be used for time history analyses in RFEM/RSTAB 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).

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

    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.

  4. Steels according to the Australian standard AS/NZS 4600:2005 in Material Library

    Material Library with Steels According to the Australian Standard AS/NZS 4600:2005

    The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
  5. TeamViewer in Help menu of RFEM and RSTAB

    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.

  6. Display of pushover curve in the calculation diagrams in RF-DYNAM Pro

    Pushover Analysis

    In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.
  7. 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
  8. 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.).

  9. 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
  10. 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.
