  • Frequently Asked Questions (FAQs)

Which Dlubal Software programs are required to calculate membrane and tensile structures?

Answer

For the structural analysis software RFEM, the special add-on modules RF‑FORM‑FINDING and RF‑CUTTING‑PATTERN are available to edit and calculate membrane and tensile structures.

The supporting/substructures can be modeled with RFEM or imported and refined by using various interfaces to various CAD solutions.

The calculation is performed according to the large deformation analysis. Furthermore, you can use the RF‑FORM‑FINDING add-on module to perform form-finding of the cable system before the calculation.

Available Programs

  • RFEM is the main program where structures, materials, and actions are defined. Planar and spatial plate, slab, shell, and member structures are possible.
  • RF-FORM-FINDING searches for the shape of member and surface models subjected to tension or compression.
  • RF-CUTTING-PATTERN determines cutting patterns for membrane structures.

More Programs and Add-on Modules

  • RWIND Simulation allows for simulations in the digital wind tunnel for complex structures. The generated wind loads can be imported into RFEM.

More add-on modules can be found in the industries of Aluminum and Lightweight Structures and Steel Structures.

Data Exchange and BIM

Various interfaces allow for efficient work in exchange with other project participants. In this way, you can also cooperate smoothly in BIM processes.

Dynamic analysis

If it is necessary to perform seismic analysis or vibration designs, the RF‑/DYNAM Pro add-on modules provide special tools for determining natural frequencies and mode shapes, an analysis of forced vibrations, a generation of equivalent loads, or for a nonlinear time history analysis.

If you have any question about the Dlubal Software programs, please do not hesitate to contact our sales department.
