Stability Analysis Software
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 Torsional Warping (7 DOF) add-on for RFEM 6 / RSTAB 9 allows you to consider the 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.
