RF-/JOINTS Steel - Rigid | Input
After starting the module, the joint group (rigid joints) is selected first, followed by joint category and joint type (rigid end plate connection or rigid splice plate connection). The nodes to be designed are then selected from the RFEM/RSTAB model. RF-/JOINTS Steel - Rigid automatically recognizes the joint members and determines from its location whether they are columns or beams. The user can intervene here.
If certain members are to be excluded from the calculation, they can be deactivated. Structurally similar connections can be designed for several nodes at the same time. The governing load cases, load combinations or result combinations have to be selected for the loading. Alternatively, you can enter the cross‑section and load data manually. The joint is configured step by step in the last input table.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- How do I create a frame joint with taper in JOINTS Steel - Rigid?
- Is it possible to use one of the RFEM/RSTAB add-on modules to design a frame corner with a docked beam, stiffeners, and any number of bolt rows?
- It is not possible to calculate the connection that I have created. Error No. 30863 appears. What should I do?
- I would like to connect a column rigidly to a girder flange. However, in the RF‑/JOINTS Steel - Rigid add-on module, beams are always connected to a column flange. How can I create a continuous beam?
- Does RF-/JOINTS Steel – Rigid allow to design a joint for the simultaneous action of an axial force and a moment for a beam-to-column connection?
- I have designed a steel connection using RF‑JOINTS and then created a model to compare it in RFEM. Why are the results not identical?
- Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
- I design a cross-section created in the SHAPE‑THIN program by using the design add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- In RF‑/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
