Generating fractal space frames

Structures under compression load are less efficient than the same structures under tension load. Instead of material breaking, yielding which determines design of a structure, at compression structures – buckling occurs before mentioned events.

By replacing straight beam elements under compression, with a series of fractal space frames (two tetrahedra on both end, and a stack of polyhedra in between) and distributing the initial compression force into tension and compression members of the space frame, R.S.Farr and Y.Mao succeeded in lowering down the amount of required material tens, several hundred times[1].
