Fachwerk & Fachwerk 3D

Fachwerk is aimed at structural engineers who analyse and design reinforced concrete structures. It intends to simplify the application of discontinuous stress fields and strut-and-tie models.

The program calculates strut-and-tie models. It only uses equilibrium conditions. Thus, unlike common programs, it does not assume elastic material behaviour.

If the modelled system is statically indeterminate, Fachwerk will nevertheless calculate the forces of the members that are determinate. One can assign forces to the remaining members. If more forces than needed to accomplish a statically determinate system are assigned to members, and the equilibrium condition is not fulfilled, Fachwerk will indicate that the system is inconsistent.
