The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
This error message is displayed if you are using a newer version of RSECTION 1 than RFEM 6.
Both versions should be on the same level in order to ensure the data compatibility of both programs, otherwise the new features of RSECTION 1 are not yet available in RFEM 6.
Make sure both versions are up to date.
In the older program generation, the add-on modules were separated from the main program, while in RFEM 6, the new add-ons are fully integrated into the main program.
It is possible to import files from RFEM 5 into RFEM 6 or RSTAB 8 into RSTAB 9. Backward compatibility of RFEM 6 with RFEM 5, as well as RSTAB 9 with RSTAB 8, is not provided.
In general, you should save the RFEM 5 or RSTAB 8 model in the latest program version before the import.
Simply open the file from the previous version in RFEM 6 or RSTAB 9 with the menu command "File > Open".
Currently, it should be possible to import most of the model data and load cases and combinations, as well as the loads, into the new program series.
Unfortunately, this does not yet include objects such as releases, connections, entries in the add-on modules, components of intersections, generated wind and snow loads, and the printout report.
We strongly recommend checking all input data again during an import and supplementing them, if necessary.
A Coupling member is a virtual member with definable rigid or hinged properties. There are four options available to couple the start and end nodes. The axial and shear forces or torsion and bending moments are directly transferred from node to node. The couplings allow you to model special situations for the force and moment transmission.
When specifying Dummy Rigid as a description of the cross-section, you can use a member with a high degree of stiffness, taking into account releases or other member properties. In RFEM 5 and RSTAB 8, Dummy Rigid was replaced by the Rigid member. However, for compatibility reasons, it is still possible to use Dummy Rigid.
The stiffnesses in these members are calculated in relation to the member length L:
where
EAx is the strain stiffness,
GIx is the torsional stiffness,
EI is the bending stiffness,
GA is the shear stiffness.
Yes, you can switch to "User-defined" in the "General" section of the "Response Spectra" tab. Then, you can use the "Import from Microsoft Excel" button to import the parameters from an Excel document.
Important Note:To avoid compatibility problems, it is helpful first to export an empty response spectrum from RF‑/DYNAM Pro, fill it in Excel, then import it again.
Yes, it is possible, for example, if a file calculated in version 5.23.01 is opened in an older version (such as 5.20.01).
The add-on modules for reinforced concrete structures have no backward compatibility. This means that the module entries must be deleted, depending on the version change.
For instance, this may be necessary if a function or feature contained in the latest program version was not available in the older version. To avoid compatibility problems, the entries in the add-on modules are removed.
In the example, the file from version 5.23.01 is opened in version 5.20.01. In this case, the entries from RF‑CONCRETE Surfaces will be lost. If you open it in version 5.17.01, for example, the entries from RF‑CONCRETE Members are also lost.
To avoid this problem, we recommend concluding a service contract and using the current version of RFEM.
The current versions of RFEM 5, RSTAB 8, SHAPE‑THIN 8, and other programs, are fully executable on Windows 10.
For older Dlubal applications, such as RFEM 4 and RSTAB 7, we cannot guarantee compatibility.
In order to provide the best possible compatibility in the BIM process, the last four TEKLA versions are supported as of our program versions X.10.01.
Thank you for your understanding.
