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.

Stability analysis

Stability Analysis According to Eigenvalue Calculation Method

RF-STABILITY/RSBUCK determines buckling modes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behaviour.

Imperfections generated in RF-IMP/RSIMP

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Models

RF-IMP/RSIMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.

Module Extension RF-/STEEL Warping Torsion | Torsional-Flexural Buckling Second Order Analysis with 7 Degrees of Freedom

Warping Torsion Second-Order Analysis with 7 Degrees of Freedom

RF‑/STEEL Warping Torsion is an extension of the RF‑/STEEL EC3 add‑on module. It performs torsional‑flexural and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.

Buckling mode

Plate Buckling Analysis for Plates With or Without Stiffeners

The PLATE-BUCKLING stand-alone program or RF-/PLATE-BUCKLING add-on module performs plate buckling analysis of rectangular plates according to the standard EN 1993-1-5.
