US Standards
The following US standards are supported in structural analysis programs by Dlubal Software:
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.
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.
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 American standard ANSI/AISC 360.
Furthermore, you can also design cold-formed steel sections according to the US standard AISI S100.
In the Steel Joints add-on, you can design connections according to the American standard ANSI/AISC 360‑16. The design procedure Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD) are already integrated.
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.
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.
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:
The Multilayer Surfaces (such as Laminate, CLT) add-on allows you to define multilayer surface structures, such as cross-laminated timber (CLT), and perform the design in the Timber Design add-on according to the American standard ANSI/AWC 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).
Safe pipelines are available for you here. 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.”

Main Program
The structural analysis program 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 can also design combined structures as well as solid and contact elements.
Main Program
The structural frame & truss analysis and design program RSTAB 9 contains a similar range of functions as the FEA software RFEM, paying special attention to frames and trusses. Therefore, it is very easy to use and for many years, it has been the best choice for the structural analysis of beam structures consisting of steel, concrete, timber, aluminum, and other materials.

Dynamic Analysis
In the Response Spectrum Analysis add-on, seismic analysis is performed using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from this. The add-on includes an extensive library of accelerograms from seismic zones. These can be used to generate response spectra.
