Fachwerk calculates strut-and-tie models used by
structural engineers for analysing and designing
reinforced concrete structures. The program only
uses the equilibrium conditions, thus it is not
assuming elastic behaviour.

This release improves the automatic model reduction algorithm. Linux users will benefit from desktop integration. The user manual has been enhanced and updated. It now covers automatic model reduction, which was introduced in the 0.4.x release.
This release adds a feature that allows semi-automatic strut-and-tie model creation: an optimization process eliminates inefficient members until the model is statically determinate.
Upon request, the program proposes member forces if the system is statically indeterminate. The calculation is linear-elastic and assumes a fixed ratio compression to tension stiffness. The algorithm works even if the system is unstable. The user still has to judge if the proposed member forces are reasonable for the given case.
