The RF-/JOINTS Steel - Pinned add‑on module allow configuration and design of shear connections of I‑beams. The design is carried out according to the following standards and guidelines:

  • EN 1993‑1‑8:2010 (including National Annexes)
  • European Recommendations for Design of Simple Joints in Steel Structures, 1st Edition 2009

There are four different types available: Web cleat connection, fin plate connection, short end plate connection, and end plate connection with cleat.

All connections are displayed as 3D graphic with the output of all necessary dimensions of sheets and angles including bolt hole arrangements. The graphics can be transferred to the printout report icluding dimension lines as well as descriptions of bolts and welds.

  2. Input

    After opening the add-on module, it is necessary to select the joint group (Pinned Joints), then the joint category and joint type (web cleat, fin plate, short end plate, end plate with cleat). Then, you can select the nodes for design in the RFEM/RSTAB model. RF‑/JOINTS Steel - Pinned recognizes the connected members automatically and determines the construction status (beam or supporting) according to their position.

    It is possible to exclude particular members from the calculation, if required. Structurally similar connections can be designed for several nodes at the same time. Loads require selection of the governing load cases, load combinations, or result combinations. Alternatively, you can enter the cross‑section and load data manually. In the last input window, the connection is configured step by step.

  3. Design

    All joint types are considered with the moment release at the column flange, or at the column web in the case of a rotated column. Therefore, the module determines the eccentric moment of a web cleat and fin plate connection, which additionally affects the bolt group at the girder flange.

    Further eccentric moments may result from the locations of the angles and sheets. In the case of cleat connection, the forces are transferred separately. Shear forces act on the cleat; tension forces and stabilizing moment are assigned to the bolts. Before the calculation, the connection is checked for geometrical plausibility; for example, the bolt hole spacing and edge distance of the bolts.

  4. Results

    The result windows list the details of all calculation results. In addition, there is a 3D graphic where you can display or hide single components as well as dimension lines and the weld data, for example. The summary shows if the individual designs have been fulfilled: The ratio level is displayed as a green data bar, which turns red if the design is not fulfilled. Furthermore, the node number and the governing LC/CO/RC are indicated.

    When selecting a design, the module shows detailed intermediate results including the actions and additional internal forces from the connection geometry. There is the option to display the results by load case and node. The connections are represented in a realistic 3D rendering that is possible to scale. In addition to the main views, it is possible to show the graphics from any perspective.

    You can add the graphics with dimensions and labels to the RFEM/RSTAB printout or export them as DXF. The printout report includes all input and result data prepared for test engineers. It is possible to export all tables to MS Excel or as a CSV file. A special transfer menu defines all specifications required for the export.
