Programs for Timber Structures

Which Dlubal Software programs can I use to calculate and design timber structures?


Both RFEM and RSTAB are ideally suited for the structural analysis and design of timber structures.

Main Programs RFEM and RSTAB

The main programs RFEM and RSTAB are used to define the model with its properties and actions. In addition to spatial frame and truss structures, such as halls or space trusses, it is possible to model plate, wall, and shell structures with RFEM. Thus, RFEM is the more versatile variant—especially if you work in other areas, such as solid construction.

Available Standards

  • EN 1995 (Eurocode 5)
  • NDS (US standard)
  • CSA O86 (Canadian standard)
  • SIA 265 (Swiss standard)
  • GB 50005 (Chinese standard)
  • AS 1720 (Australian standard)

Add-ons for Timber Structures

Design add-ons supplement the functionality of the main programs. Use the Timber Design add-on to perform the ultimate and serviceability limit state design checks as well as the stability analysis and fire resistance design according to the standards listed above. In combination with the Torsional Warping (7 DOF) add-on, you can also perform lateral-torsional buckling analysis with up to seven degrees of freedom.

The special-solution Multilayer Surfaces add-on for RFEM is ideally suited for laminate surfaces made of cross-laminated timber (CLT).
