Analysis & Design Software for Tensile Membrane Structures

The structural analysis software RFEM 6 is the basis of a modular program family. The main program RFEM 6 is used to define structures, materials, and loads of 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.

• Main Program RFEM 6

The RWIND 2 stand-alone program is recommended for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

The Form-Finding add-on for RFEM 6 search for the optimal shape of the members subjected to axial forces and the surface models subjected to tension. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions. The resulting new model shape with impressed force conditions is made available as a universally applicable initial state for further calculation of the entire structure.

The Nonlinear Material Behavior add-on for RFEM 6 allows you to consider material nonlinearities in RFEM.

There is the option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D." This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.

The RF‑CUTTING‑PATTERN add-on module for RFEM 5 calculates and organizes cutting patterns for membrane structures. Boundary conditions of the cutting patterns on curved geometry are determined by boundary lines and independent planar cutting lines or geodesic cutting lines. The flattening process is performed according to the minimum energy theory.
