Structural calculation software for timber truss


Design, check and optimise timber trusses sizes. APF WoodTruss aids in the analysis and design of timber frame trusses (King post, Queen post, Fink, Howe, Fun, Scissor)

APF WoodTruss lets you design timber trusses (King post, Queen post, Fink, Howe, Fun, Scissor), according to Eurocode 5 (EC5).

All You have to do is specify the dimensions, the constraints and the loads. APF WoodTruss creates the load combinations according to Eurocode 0 and Eurocode 1 and performs all the required checks for ULS and SLS.

APF WoodTruss reports warns you in case of unacceptable design of the timber structure

The results are displayed in the graphic environment and the user can save a detailed report with calculation details and images.

The user interface is designed to simplify your work. You can change every value (cross sections’ size, truss span, etc.), recalculate and the results are immediately available.

All the design variables, such as load coefficients, material properties (mechanical properties of timber) can be adjusted by you, according to your needs (or the requirements of any National Standard or National annex to the Eurocodes).

APF WoodTruss performs a finite element analysis of the timber truss, as a two dimensional timber structure, with the supports having the degree of stiffness selected by the user.

Internal forces, support reactions and deflections are displayed by the graphical interface separately for each load case and for every timber frame trusses (tie beams, rafters, struts).

APF WoodTruss performs structural fire design according to Eurocode 5, using the reduced cross section method, for both unprotected and protected surfaces. Surfaces can be protected by fire protective claddings whose properties are defined by the user.

APF WoodTruss allow the user to proceed with a perfect structural design of timber truss with a complete calculation report, a CAD exportation and also allowing the user to export the timber joints to our APF WoodJoint

parallax background



Design, check and optimization of timber structures (Fink truss, Howe truss, etc.).

  • Design timber trusses:
    - king post truss
    - queen post truss
    - Fink truss
    - Howe truss
    - Fan truss
    - Scissor truss
  • Check strength, buckling, and deformations (you can choose which checks to perform)
  • Structural fire design, for both unprotected and protected surfaces
  • Design is in accordance with Eurocode 5 (EN 1995-1-1:2004 + A1:2008 + A2:2014). All nationally determined parameters are editable
  • Quick summary of utilization factors
  • Takes into account the contribution of deformation due to shear in deflection calculations
  • Outputs figures and charts in JPEG or PNG, outputs drawings in DXF
  • Clear and easy to read report in HTML or DOCX
  • Materials covered:
    - solid timber (softwoods, EN338:2009 C14 ÷ C50; hardwoods, EN338:2009 D18 ÷ D70)
    - glulam (EN 14080:2013 GL20h ÷ GL32h, GL20c ÷ GL32c)
  • You can add any number of concentrated or distributed loads
  • Load Combinations are defined automatically (with support for custom combinations)
  • You can add any number and type of supports and define their stiffness
  • Semi-rigid connections (as percentage of restrained rotation)

The new releases are coded to be launched after the MicroSoft .NET 6.0 Desktop App installation that could be downloaded at this LINK.
