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 AISC for steel members).

In addition, RFEM and RSTAB provide powerful add-on modules for plate buckling design, buckling analysis, and much more.

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, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural 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 behavior.

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Models

The RF-IMP/RSIMP add-on module 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 flexural-torsional 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.

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.
