Timber Structural Analysis & Design Software

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.

Analysis & Design of Frame/Beam/Truss Structures

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to to beam, frame, or truss structures. Therefore it is very easy to use and for many years it has been the best choice for structural frame analysis and design of timber structures.

Timber Design According to Various Standards

The following add-on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as stability analyses for timber.

  • RF-/TIMBER Pro (incl. fire resistance) according to EN 1995‑1‑1 (Eurocode 5) and SIA 265 (Swiss standard)
  • RF-/TIMBER AWC (incl. fire resistance) acc. to ANSI/AWC NDS‑2012 and ANSI/AWC NDS‑2015 (US standards)
  • RF-/TIMBER CSA according to CSA 086‑14 (Canadian standard)
  • RF-/TIMBER NBR according to NBR 7190:1997 (Brazilian standard)
  • RF-/TIMBER SANS according to SANS 10163‑1:2003 and SANS 10163‑2:2001 (South African standards)

Design of Laminate Surfaces

RF-LAMINATE performs stress and deflection analysis of laminate surfaces such as cross‑laminated timber plates (CLT).

Structural Design of Timber Connections

Here you can find numerous add-on modules for the design of joints in steel and timber structures.

Stand-Alone Programs RX-TIMBER

Stand-alone programs of the RX‑TIMBER family perform designs of the ultimate limit state, serviceability limit state and fire resistance for different structural components according to Eurocode 5.

    Vibration Design of Cross-Laminated Timber Plates

    For wide-span ceilings, the vibration design of cross‑laminated timber plates is often governing. The advantage of the lighter material of timber over concrete turns into a disadvantage because a high mass material is advantageous for a low natural frequency.
