Stability Analysis Software
Stability Analysis of Structures
Stability analysis is necessary particularly for structural components subjected to compression and bending. Generally, stability analysis is performed in the corresponding add-on module for the relevant material (for example in RF-/STEEL EC3 for steel members).
In addition, RFEM and RSTAB provide powerful add-on modules for plate buckling design, buckling analysis, 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.
Stability Analysis According to Eigenvalue Calculation Method
RF-STABILITY/RSBUCK determines buckling shapes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behavior.
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.
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.
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.
