Nonlinear Structural Analysis Software

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. 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 & Design of Frame/Beam/Truss Structures

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analyses.

Application of Nonlinear Material Laws

RF-MAT NL allows you to apply the nonlinear material laws in RFEM.

Plastic Design of Cross-Sections

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

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

    When designing column bases, high performance anchors are often used for an anchorage. This article describes different models and their evaluation.

    Comparison of Plastic Design (Shell Model) and Nonlinear Member Model

    The following example presents a comparison between a shell model and a simple member model performed in RFEM. In the case of the shell model, a beam is suspended within surfaces and modelled with restraints on both sides due to the boundary conditions. This is a statically indeterminate system that will form plastic hinges when overloaded. The comparison is carried out on a member model, which has the same boundary conditions as the shell model.
