Analysis & Design Software for Tensile Membrane Structures

The successful structural analysis program RFEM 6 by Dlubal Software is the basis of a modular program family that you can customize and combine according to your precise requirements. In the main program RFEM, you can define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Furthermore, you can create combined structures as well as model solid and contact elements.

• Main Program RFEM 6

Do your structures have to withstand every gust of wind? Then it is best to use the Dlubal stand-alone program RWIND 2. It is particularly recommended for complex model shapes. There are wind flows around all structures simulated in a digital wind tunnel.

You can easily import your generated wind loads acting on these objects into RFEM or RSTAB. Thus, you can complete your project there.

Leave your form-finding to the program: The corresponding Form-Finding add-on for RFEM 6 finds an optimal shape of members subjected to axial forces and surface models subjected to tension. The shape is precisely 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 available for you as a universally applicable initial state for further calculation of the entire structure.

• Form-Finding Add-on for RFEM 6

When working with nonlinear material models, you can rely on the Nonlinear Material Behavior for RFEM 6 add-on module. It gives you 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 ETFE foils, for example.

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.

• Aluminum and Lightweight Structures

The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) to read or write the data from or to RFEM and RSTAB.

Customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work.
