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