Nonlinear Structural Analysis Software

Consideration of 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 design of cables, for example). Moreover, RFEM supports the consideration of material nonlinearities such as plastification, concrete in cracked state, and many others.

FEM Analysis and Design of Structures

The structural analysis program RFEM is the basis of a modular software system. 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.

Analysis and Design of Beam Structures

The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM. Due to the special attention to frameworks, it is even easier to use.

Application of Nonlinear Material Laws

The RF-MAT NL add-on module allows the application of nonlinear material laws in RFEM.

Plastic Design of Cross-Sections

The RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module. It allows for plastic design of cross‑sections according to Partial Internal Forces Method or Simplex Method.

Nonlinear Analysis of Reinforced Concrete

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

Interfaces for Data Exchange

The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.
