Implemented US Standards
Automatic Generation of Combinations in RFEM and RSTAB
Are you planning your structures for the USA? Then you have come to the right place. In RFEM 6 / RSTAB 9, you can automatically generate load and result combinations according to the US standards ASCE 7/SEI, ASCE/SEI 7 (NDS), ACI 318, and IBC.
Design of Reinforced Concrete Members, Columns, and Surfaces According to Standard ACI 318
When working with reinforced concrete, you are supported by the Concrete Design add-on for RFEM 6 / RSTAB 9. Here, you can design reinforced concrete members, columns, and surfaces according to the American standard for reinforced concrete design ACI 318.
Steel Design According to AISC 360
Keep an eye on the usability and standards of your steel structures. The Steel Design add-on for RFEM 6 / RSTAB 9 performs the ultimate limit state and the serviceability limit state design of members according to the US standard ANSI/AISC 360.
Design of Aluminum Members According to ADM
Make sure you design your aluminum structures safely and in accordance with standards. The Aluminum Design add-on for RFEM 6 / RSTAB 9 performs the ultimate limit state and the serviceability limit state design of members according to the US standard ADM.
Design of Timber Members According to ANSI/AWC NDS
If you design timber structures, then this way, please. The Timber Design add-on for RFEM 6 / RSTAB 9 performs the ultimate limit state, serviceability limit state, and fire resistance design checks according to the American standard ANSI/AWC NDS.
Seismic Design According to IBC, ASCE/SEI
The safety of your structures even under turbulent conditions is easy and efficient to design using these add-ons.
The Modal Analysis add-on for RFEM 6 / RSTAB 9 allows you to determine natural frequencies and mode shapes.
In the Response Spectrum Analysis add-on for RFEM 6 / RSTAB 9, the seismic analysis is performed for you using the multi-modal response spectrum analysis. Among others, the following US standards are implemented:
Design of Laminate Surfaces According to ANSI/AWC NDS
You have come to the right place to keep your laminate surfaces usable and conform to standards. The RF-LAMINATE add-on module for RFEM 5 / RSTAB 8 allows you to perform stress and deflection analysis of laminate surfaces (for example, CLT, GRP) according to the standards ANSI/AWC NDS (LRFD and ASD).
Design of Indirect Timber Connections According to NDS
For connections between steel and timber, you find the right solution here. In the RF-/JOINTS Timber - Steel to Timber add-on module for RFEM 5 / RSTAB 8, you can design the joints indirectly connected by means of steel plates according to the American standard ANSI/AWC NDS (LRFD and ASD).
Stress Analysis of Pipelines According to ASME B31.1 and ASME B31.3
Safe pipelines are available here for you. RF-PIPING Design is used for the precise design of pipelines. The module compares the existing pipe stresses with the allowable stresses according to ASME B31.1 and ASME B31.3, among other standards.

Frequently Asked Questions (FAQ)Customer Projects
Fascinating customer projects designed with the Dlubal structural analysis software.
“I’ve used many FEA programs over the years and I would rank RFEM at the top. Very powerful with many options for modeling and displaying information while still being intuitive and easy to use from a common sense standpoint. In my opinion, RFEM is in a class of its own.”

- Is it possible to perform a calculation in RF‑CONCRETE Members or RF‑CONCRETE Columns with the user-defined material (yield strength)?
- How are the effective lengths of frame columns determined in RFEM or RSTAB?
- When importing a cross-section from RSECTION 1, I get an error message regarding the version. What can I do?
