The design of rigid end plate connections is particularly complex for four-row connection geometries and multi-axis bending stresses because there is a lack of official design methods.

After activating the RF‑PIPING add‑on module, a new toolbar is available in RFEM and the project navigator and tables are extended. Piping modeling is performed in a similar way as members. Pipe bends are defined by using tangents (straight pipe sections) and bend radius at the same time. Thus, it is easy to subsequently change bend parameters.
It is also possible to extend the piping subsequently by defining special components (expansion joints, valves, and others). The implemented libraries of structural components facilitate the definition.
Continuous pipe sections are defined as sets of piping systems. For piping loads, member loads are assigned to the respective load cases. The combination of loads is included in piping load combinations and result combinations. After the calculation, you can display deformations, member internal forces and support forces graphically or in tables.
Pipe stress analysis according to standards can then be performed in the RF‑PIPING Design add‑on module. You only need to select the relevant sets of piping systems and load situations.
Frequently Asked Questions (FAQs)
- How can I display the stresses in the stress points in RF‑STEEL Members?
- What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?
- I compare the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis including imperfections. The differences are very large. What is the reason?
- Why do I obtain much higher design ratios in RF‑/STEEL than for cross-section design in RF‑/STEEL EC3?
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- For a cross-section from the cross-section library of RFEM/RSTAB, the stresses calculated with RF‑/STEEL differ from the stresses of the same cross-section calculated with SHAPE‑THIN. What is the reason?
- Why RF‑/STEEL does not display the same maximum internal forces when calculating a result combination, as it is in the results of the result combination itself?
- I used double members when entering members. Do I have to consider anything else or is it better to enter a member with double cross-section properties?
- In RFEM / RSTAB, I use cross-sections whose values are defined by direct input. How do I get the RF- / STEEL module to consider my cross-sections?
- In the dimensioning module, a DUENQ cross-section is classified as an invalid cross-section type and dimensioning is therefore not possible. What is the reason?
