Nonlinear Structural Analysis Software

Geometry and Material Nonlinearities

In the structural analysis programs RFEM and RSTAB, it is possible to consider member nonlinearities (for example failure at compression/tension, slippage, tearing, creeping) as well as support and release nonlinearities such as failure, creeping, friction support, and so on.

In addition to linear static analysis and second-order analysis, there is also large deformation analysis available (for cable design, for example). Moreover, RFEM supports the consideration of material nonlinearities such as plastification, concrete in cracked state (state II), and many others.

Structural FEM Analysis and Design

The structural analysis software RFEM 6 is the basis of a modular program family. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as model solid and contact elements.

Structural Frame & Truss Analysis Software

The structural frame analysis software RSTAB 9 has a similar range of functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years, it has been the best choice for structural analysis and design of pure structural member models.

Consideration of Nonlinear Material Laws

The Nonlinear Material Behavior add-on for RFEM 6 allows you to consider nonlinear material behavior in RFEM (for example, isotropic plastic, orthotropic plastic, isotropic damage).

Plastic Design

RF‑/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add-on module for RFEM 5 / RSTAB 8. This allows for the plastic design of cross-sections according to the partial internal forces method (TSV) and simplex method.

Nonlinear Design of Reinforced Concrete

The RF‑CONCRETE NL add-on module for RFEM 5 performs physical and geometrical nonlinear calculation of beam and plate structures consisting of reinforced concrete. The RF CONCRETE Deflect add-on module for RFEM 5 allows for analytical deformation analysis of plate structures consisting of reinforced concrete.

Interfaces for Data Exchange

The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.

The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.

Support and Learning

Customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work.
