"Michell Structures"

The Generative Component practical last Thursday was very interesting, the possibilities for making complicated geometries seemed very usable for a model I would like to make for the geometry of the bridge.
But to make such a structure you need proper constraints and a theory to use as a base for its form.
Andrew and Eliza told me that in the first place all the forces in the bridge can be dissolved into the direction of the span of the bridge. So the spatial construction of the bridge is probably still going to be a quite 2D construction. But what the exact form of it is going to be is still quite hard to tell. Andrew put a reader online about special structures, in this by name the ‘Michell Structures’ are very interesting. These structures are defined by removing material until a specific wireframe remains. After this process he tries to find a mathematical solution that goes with each wireframe.
I’m going try to use this theory as a help to create the shape for the bridge.

But to make the geometry there are more constraints needed. With Andrew we also talked about the composition of several complex geometries. The best base for this is mostly still the triangle. So this is a clear constraint to begin with. Beside that the spaghetti has also a maximum length of about 20 centimetres.

The forthcoming days I’m going to practise with GC and I’m going to try to extract some data out of Diana that is useful to make a first shape.

  1. So probably a 2D construction. There is a simple game to make dynamic 2D constructions:
