Nonlinear Structural Analysis Software

The structural analysis software RFEM 6 is the reliable basis of a modular program family. Use RFEM to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Are there different elements involved in your project? You can also calculate combined systems as well as model solid and contact elements.

If you want to create pure member structural models, we recommend you the spatial frame & truss analysis program RSTAB 9. With RSTAB, you get a similar range of functions as with the structural FEA software RFEM. The special attention to beam, frame, and truss structures facilitates the user interface and thus also the operation of the software. Many structural engineers have already trusted RSTAB with their structural analysis models – and have been doing so for years. Become one of them!

Material behavior is an important factor to be considered in your project. This also includes disproportionate discrepancies, such as the nonlinear behavior of building materials. To model your project as safely and precisely as possible, the Nonlinear Material Behavior add-on for RFEM 6 is a great help. It allows you to consider nonlinear material behavior in RFEM (for example, isotropic plastic, orthotropic plastic, isotropic damage). Use it to avoid any unpleasant surprises.

The design of cross-sections is an important part of structural analysis. RF‑/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add-on module for RFEM 5 / RSTAB 8. Using this extension, you can effortlessly perform the plastic design of cross-sections according to the partial internal forces method (TSV) and simplex method. Structural analysis can be that simple.

Do you need a program that can do more? For example, physical and geometrical nonlinear calculation of reinforced concrete beam and plate structures? Then we have the right thing for you: the RF‑CONCRETE NL add-on module for RFEM 5. Moreover, the RF‑CONCRETE Deflect add-on module for RFEM 5 allows for analytical deformation analysis of plate structures consisting of reinforced concrete – exactly what you need.

The Building Information Modeling (BIM) process is an important part of daily work for structural and civil engineers. That's why we have ensured that the Dlubal structural analysis software can be seamlessly integrated into the BIM process. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) to read or write data from or to RFEM and RSTAB.

Customer satisfaction is important to us. Therefore, customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work. Your Dlubal team is here for you!
