Stability Analysis Software

Stability Analysis of Structures

A completed structural analysis project looks like attractive as this: First and foremost, it has to be stable, of course. Especially for structural components subjected to compression and bending, the corresponding stability analysis has to be performed. In Dlubal programs, the stability analysis is included in the respective add-ons for the relevant building material (for example, steel members are analyzed in Steel Design for RFEM 6 / RSTAB 9).

Furthermore, RFEM and RSTAB provide powerful add-ons and add-on modules for plate buckling design, buckling analysis, and much more. Thus, you can find exactly what makes your project even safer.

Structural FEM Analysis and Design

Are you still looking for a convenient structural analysis program? Then you are right here! RFEM 6 is the basis of a modular program family. In the main program RFEM, you can define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Here you can also create combined structures as well as to model solid and contact elements. Read more about RFEM 6 here:

Structural Frame & Truss Analysis Software

It becomes more special with the spatial frame & truss analysis program RSTAB 9. The range of functions of the RSTAB product range is similar to that of the FEA software RFEM. However, due to the special attention to beam, frame, and truss structure, it is very easy to use. It is not for nothing that for many years, RSTAB has been the best choice for structural analysis and design of pure structural member models.

Stability Analysis According to Eigenvalue and Incremental Method

The Structure Stability add-on for RFEM 6 / RSTAB 9 is a true multi-talent. It calculates critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, it is suitable for linear and nonlinear analysis of structural stability behavior.

Warping Torsion Second-Order Analysis with 7 Degrees of Freedom

What sounds complicated doesn't always have to be complicated. At least not with the right program by your side. The Warping Torsion add-on (7 degrees of freedom) for RFEM 6/RSTAB 9 allows you to consider cross-section warping as an additional degree of freedom when calculating members in RFEM and RSTAB.

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Structures

There are numerous helpful add-on modules for RFEM 5 / RSTAB 8. For example, RF‑IMP/RSIMP for RFEM 5 / RSTAB 8 is used to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model. Discover innovative possibilities in structural engineering with Dlubal Software.

Plate Buckling Analysis for Plates with or Without Stiffeners

In addition to the main Dlubal programs with their add-ons, there are also stand-alone programs available for you. The PLATE-BUCKLING stand-alone program is one of them, and performs plate buckling analysis of rectangular plates according to the standard EN 1993‑1‑5. The same range of functions is included in the RF‑/PLATE‑BUCKLING add-on module for RFEM 5 / RSTAB 8.

Interfaces for Data Exchange

The Dlubal structural analysis software also enables you to work together. It can be seamlessly integrated into the Building Information Modeling (BIM) process. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) to read or write the data from or to RFEM and RSTAB.
