The existing loading is compared to the load resistances stored in the database. The program also performs the interaction of internal forces M, N, and Q.
After the design, all results are displayed in clearly arranged result tables; for example, by load case or by node.
You can visualize the joints graphically in the add-on module or in RFEM/RSTAB. In addition to the input and result data, including design details displayed in tables, you can add all graphics into the printout report. This way, comprehensible and clearly arranged documentation is guaranteed.

After opening the add-on module, it is necessary to select the joint type (end plate or bracket). You can select the individual nodes graphically in the RFEM/RSTAB model.
The RF-/JOINTS Steel - SIKLA add‑on module checks the cross‑section and materials of the connected members. It is possible to model and design structurally similar connections on several locations in the structure.

- Numerous component types, such as base and end plates, web angles, fin plates, gusset plates, stiffeners, tapers, or ribs for easy input of typical connection situations
- Universally applicable basic components (such as plates, welds, bolts, auxiliary planes) for modeling complex connection situations
- Graphical display of the connection geometry with dynamic updating during the input
- Wide range of cross-section shapes: I-sections, U-sections, angles, T-sections, hollow sections, built-up cross-sections and thin-walled sections
- Library in the Dlubal Center with a large number of program-side template connections, including user-defined templates
- Automatic adaptation of the connection geometry based on the relative arrangement of the components to each other – even in case of subsequent editing of the structural components
