Trusses Timber
FWH+
The program is suitable for the structural analysis and design of timber trusses commonly used in portal frame construction. Different cross-sections and materials can be defined for chords, posts or diagonal struts. Continuous chords can be considered flexurally rigid members.

Design
Depending on the selected truss system, the individual load cases and, subsequently, the load case combinations to be investigated are determined. The individual member forces for the different load cases are calculated based on the strut-and-tie theory. The maximum internal forces are determined for the following types of members:
- Top chord
- Bottom chord
- Post
- Diagonal member
The support reactions are always determined for the simple loads. Optionally, you can put out the loads on the supports separately for the different action groups.
