The RF-/HSS add‑on module analyzes various hollow section connections or designs an existing connection.

It is possible to design planar and spatial truss nodes containing round, square or rectangular hollow sections.

RF-/HSS performs the ultimate limit state design according to the requirements of the following standard:

  •  EN 1993‑1‑8:2005 + AC:2009

  1. Features

    • Integration in RFEM/RSTAB with automatic geometry recognition and transfer of internal forces
    • Optional manual definition of connections
    • Extensive library of hollow sections for chords and struts:
      • Round sections
      • Square sections
      • Rectangular sections
    • Implemented steel grades: S 235, S 275, S 355, S 420, S 450, and S 460
    • Various types of connections available, depending on the standard specifications:
      • K connection (gap/overlapping)
      • KK connection (spatial)
      • N connection (gap/overlapping)
      • KT connection (gap/overlapping)
      • DK connection (gap/overlapping)
      • T connection (planar)
      • TT connection (spatial)
      • Y connection (planar)
      • X connection (planar)
      • XX connection (spatial)
    • Selection of partial safety factors according to the National Annex for Germany, Austria, Czech Republic, Slovakia, Poland, Slovenia, Switzerland, or Denmark
    • Adjustable angles between struts and chords
    • Optional chord rotation of 90° for rectangular hollow sections
    • Consideration of gaps between struts or overlapping struts
    • Optional consideration of additional nodal forces
    • Design of the connection as the maximum load-bearing capacity of the struts of a truss for axial forces and bending moments
  2. Input

    It is possible to select connection nodes graphically in the RFEM/RSTAB model. The relevant cross-section data and geometry are imported automatically. You can also define the parameters of hollow section connections manually. If necessary, you can modify the sections in the module.

    The default angle between struts and chords can be modified as well. The geometric relation of the struts to each other is important for the correct choice of design. This relationship can be defined by specifying a gap between the struts or by overlapping them.

  3. Design

    A successful design check is based on the plausibility check of the geometric conditions.

    The RF-/HSS add-on module performs the calculation for the following designs:

    • Flange failure of chord member due to normal force
    • Shear failure of chord member due to normal force
    • Strut failure due to normal force
    • Punching shear due to normal force
  4. Results

    The design includes detailed information about analyzed internal forces, validity limits, and design conditions. Design failures are clearly marked in the result overview.

    All input and result data are also documented in the general RFEM/RSTAB printout report. Separate design cases allow flexible analysis of the individual components in large structures.
