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.

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.

Wind Simulation & Wind Load Generation

The RWIND Simulation 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.

Form-Finding of Membrane Structures

RF‑FORM‑FINDING searches for shapes of structures subjected to tension or compression, such as membrane and cable structures. The shape is calculated by the equilibrium between the surface stress (specified prestress and additional load such as self‑weight, pressure, etc.) and the given boundary requirements. The prestressed model is afterwards used as the initial state for all subsequent calculations.

Cutting Patterns of Membrane Structures

RF‑CUTTING‑PATTERN generates 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.

Consideration of Nonlinear Material Laws

The RF-MAT NL add-on module allows for consideration of nonlinear material behavior in RFEM.

It offers 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" (RF-MAT-NL add-on module required). This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.

Doctoral Thesis on Membrane Structure Design According to FEA

This PhD thesis by Rostislav Lang deals with the design and analysis of membrane structures using FEA software.

Versatile Software and Great Service

"ACS Production chose RFEM in order to have a versatile software that allows us to design our tensile membranes alongside our steel, timber, or aluminum structures in a single user environment.

The software’s capabilities and user-friendly interface are a real advantage over the competition. What’s more, the customer support’s dedication, modernness, responsiveness, and skillset ensure that each and every one of our projects is properly realized."
