  1. Torsional Stress in the Intersection Points of a Cross-Laminated Timber Panel in RFEM

    Torsional Design in RF-LAMINATE

    In the RF-LAMINATE add-on module for RFEM, the design of torsional shear stresses is possible in the superposition of net and gross cross-section values. The design is effected separately each in x- and y-direction. The loadings of the intersection points of cross-laminated timber panels are designed.
  2. 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
  3. 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.).

  4. 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
  5. 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.

    RF-/LIMITS | Results

    At first, the governing connection designs are displayed by the respective load case and load or result combination. In addition, it is possible to display results separately for sets of members, surfaces, cross-section, members, nodes, and nodal supports.

    You can reduce the results displayed by means of the filter function and thus create a clearly-arranged result overview.
