Free-form thrust lines
Structures with a non-funicular shape can be transformed into a free-form thrust line by adding a tension stiffening system shaped according to the bending moment in the free-form curve. The reaction forces of the stiffened free-form structure will be equivalent to those of the funicular solution (dash-dotted line). Explore possible configurations of the free-form thrust line. Note that the stiffening system shown is the visualization of the bending moment in the free-form curve, not the actual geometry of the structure.
