Stability Analysis Software
Structural FEM Analysis and Design
The structural analysis software RFEM 6 is the basis of a modular program family. The RFEM main program 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.
Structural Frame & Truss Analysis Software
The structural frame analysis software RSTAB 9 has a similar range of functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years, it has been the best choice for structural analysis and design of pure structural member models.
Stability Analysis According to Eigenvalue and Incremental Method
The Structural Stability add-on for RFEM 6 / RSTAB 9 calculates critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, it is suitable for the linear and nonlinear analysis of the structural stability behavior.
Warping Torsion Second-Order Analysis with 7 Degrees of Freedom
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
The RF‑IMP/RSIMP add-on module for RFEM 5 / RSTAB 8 is used to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model.
Plate buckling analysis for plates with or without stiffeners
The PLATE‑BUCKLING stand-alone program or the RF‑/PLATE‑BUCKLING add-on module for RFEM 5 / RSTAB 8 allow for buckling safety design of rectangular plates according to the standard EN 1993‑1‑5.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
Support and Learning
Customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work.
