Steel Joints for RFEM 6

Product Description

  • FE-BUCKLING Stand-Alone Program




  • Analysis of steel joints via automatic generation of an FE model from the connection in the background
  • Consideration of all internal forces in the design (N, Vy, Vz, My, Mz, and Mt), no restriction to planar loading
  • Automatic transfer of the loading of all load combinations at all selected nodes into the FE model
  • Time-saving modeling for complex connection situations, the generated FE model can also be saved and used for your own detailed analyses
  • Extensive, extensible library with predefined steel connection templates
  • Can be used for any connections with rolled and welded cross-sections; I‑sections, U‑sections, angles, and T‑sections are currently available 

Connection Components

  • Many predefined components available for easy input of typical connection situations (for example, end plates, cleats, fin plates)
  • Universally applicable basic components (plates, welds, bolts, auxiliary planes) for entering complex connection situations
  • Graphical display of the connection geometry that is updated in parallel with the input
  • The Steel Joints Template included in the Add-on allows you to select from several connection types and, when selected, is applied to your model
  • In the Template, there are connections from 3 general categories: Rigid, Pinned, Truss
  • Automatic adaptation of the connection geometry, even if the members are subsequently edited, due to the relative relation of the components to each other

Plausibility Check

  • Parallel to the input, a plausibility check is carried out by the program to quickly detect missing input or collisions, for example
  • When an error is found, an error message appears describing the problem



  • The design of the connection components is performed according to Eurocode EN 1993-1-8
  • After activating the Add-on, the design situations for Steel Connections must be activated in the "Load cases and Combinations" dialog box
  • For the design of the connection stability (Buckling), it is necessary to have the Add-on Structure Stability activated
  • The calculation can be started via the table or via the icon in the top bar

Design According to EN 1993-1-8

The program can also help you here. It determines the bolt forces on the basis of the calculation on the FE model and evaluates them automatically. You can perform the design checks of the bolt resistance for the failure cases tension, shear, hole bearing, and punching shear according to the standard. The program takes care of everything else in this step. It determines all the necessary coefficients and displays them clearly.

Do you want to perform weld design? The required stresses are also determined on the FE model in that case. Then, the design is carried out with the partial safety factors according to the selected National Annex.

You can perform the plate design plastically by comparing the existing plastic comparison strain to the allowable plastic strain (5% according to EN 1993‑1‑5, Annex C, or user-defined specification).
