Strut, Nucleated

Nucleated struts are one morphology of strut: others are straight, curved, or ring.


In a nucleated strut, the strut radiates in multiple directions, and integrates its compression in a nucleated core. Snelson's x-extender and Levin's spinal nucleated tetrahedron are both examples of nucleated struts. The V-Expander is an example of a partically nucleated strut, as only two struts from its core.

In Fuller's most far-reaching conception, the nucleated strut is the mass center of the atom, held in place by the tension of gravitation.

Nucleated Struts in Motro's Writings

Motro discusses Anthony Pugh's nucleated models. He wrote, "A first one comprised four triangular compressed components inside a net of tensile ones. The overall geometry was organized according to a cuboctahedron, one of the semi regular polyhedra. The second model was very surprising since the struts constituted a single circuit with 15 nodes and 15 compressed components. For this model, the cables are the edges of a polyhedron with two pentagonal bases. The third one is a twenty-strut four-layer circuit pattern system. There are represented on Figure 15. This presentation concerns only the second cell."
