Offshore Structural Analysis & Design Software

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 determines internal forces, deformations and support reactions. For subsequent design, the add‑on modules are available to consider structural conditions of specific material and standards. Due to the modular concept of the software, you can combine the programs to meet your individual requirements.

    Stresses for Weld Seam Design

    In RF-STEEL Surfaces, it is possible to display the stresses relevant for the design of welds according to EN 1993‑1‑8, Figure 4.5, for example. When evaluating the stress ratio, the local axis system xyz of surfaces has to be taken into account.
