Analysis & Design Software for Tensile Membrane Structures

Structural Engineering Software for Tensile Membrane Structures

The structural analysis software RFEM allows for form‑finding, structural analysis, and determination of cutting patterns of tensile membrane and cable structures.

The calculation is performed according to the large deformation analysis. When determining the cutting patterns, user‑defined intersection lines and compensation dimensions are considered.

Structural FEM Analysis and Design

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 to model solid and contact elements.

Form-Finding of Membrane Structures

The Form-Finding add-on for RFEM 6 searches 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.

Consideration of Nonlinear Material Laws

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.

Cutting Patterns of Tensile Membrane Structures

The RF‑CUTTING‑PATTERN add-on module for RFEM 5 calculates and organizes cutting patterns for membrane structures. The 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.

Add-ons and Add-on Modules for Structural Analysis of Tensile Membrane Structures

For the structural analysis and design of tensile membrane structures or their substructures, we recommend the add-ons and add-on modules of the Steel Structures and Aluminum and Lightweight Structures industries.

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.
