Analysis & Design Software for Aluminium and Lightweight Structures

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 contains a similar range of functions as RFEM. Due to the special attention to beam, frame and truss structures, it is very easy to use.

Aluminium Design According to Various Standards

The following add-on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as stability analyses for aluminium members and sets of members.

Form-Finding and Design of Cable and Membrane Structures

RFEM and RSTAB provide various options for form‑finding and design of cable and membrane structures. For example, the RF‑FORM‑FINDING add‑on module can find the shape of cable and membrane structures.

The RF‑CUTTING‑PATTERN add‑on module generates and organizes cutting patterns for membrane structures.

    Form-Finding in RFEM

    The RF-FORM-FINDING add-on module determines equilibrium shapes of membrane and cable elements in RFEM. In this calculation process, the program searches for such a geometric position in which the surface stress/prestress of membranes and cables is in equilibrium with natural and geometric boundary conditions. This process is called form-finding (hereinafter referred to as FF). The FF calculation can be activated in RFEM globally in the "General Data" of a model, "Options" tab. After selecting the corresponding option, a new load case or a calculation process called RF-FORM FINDING is created in RFEM. An additional FF parameter is available for defining surface stress and prestress when entering cables and membranes. By activating the FF option, the program always starts the form-finding process before the pure structural calculation of internal forces, deformation, eigenvalues, etc., and generates a corresponding prestressed model for further analysis.
