Knowledge Base Articles

Not all structural elements of a real building are included in a structural model. As an example, we can look at a pipe that runs along a steel girder frame.

It may become necessary to analyze pipe cross‑sections as surface models in plant engineering in particular, but also when analyzing details of structural systems. For this purpose, RFEM offers the option to create pipe cross‑sections automatically by means of a line.

In many cases, it is necessary to filter the results for the display of values on surfaces so as not to show all the numbers. In displaying the reinforcement arrangement, you can, for example, hide values that are below the already used basic reinforcement.

Saving and Importing Diagrams for Member Hinges

In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member hinges. In addition to the nonlinearities "Fixed if" and "Partial activity", you can select "Diagram". If you select the "Diagram" option, you have to specify the according settings for the activity of the member hinge. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the hinge.

Product Features

Graphical Representation of Pipelines with Loads in RFEM

After activating the RF‑PIPING add‑on module, a new toolbar is available in RFEM and the project navigator and tables are extended. The piping system is now modeled in the same way as the members. Pipe bends are defined simultaneously by tangents (straight pipe sections) and radius. 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.

Graphical Representation of Pipeline Analysis Results in RFEM

After modeling piping systems in RFEM using RF‑PIPING and defining loads as well as load and result combinations, you can carry out pipe stress analysis in the RF‑PIPING Design add‑on module.

You can select all or only some pipelines and loads, load or result combinations for piping design. The material library provides various materials according to EN 13480‑3, ASME B31.1‑2012, and ASME B31.3‑2012 standards.

After the calculation, the results are displayed in clearly arranged windows; for example, by cross‑section, by pipeline, or by members. You can also display the design ratio graphically on the entire model in RFEM. This way, you can quickly recognize critical or oversized areas of the cross-section.

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. You can select the report contents and extent specifically for the individual designs.

Frequently Asked Questions (FAQ)

I design pipelines using the RF-PIPING Design add-on module. I have created a new prestress load case and loaded the piping with longitudinal displacement.
Is it possible to add this new load case to combinations that are generated automatically?

Is it possible to automatically generate zones in RWIND 2?

How can I create a response spectrum according to ASCE 7‑22?

I have display problems in RFEM 6, RSTAB 9, and RSECTION 1, or the program crashes immediately after starting it. What options do I have to improve this?

How can I adjust font sizes in RFEM 6 and RSTAB 9 for a screen view and a printout report?

In the case of stairs with a complicated geometry, it is often difficult to design welds by using the analytical methods. How can I do this with RFEM?
