Tensegrity

The essay "Tensegrity" by Buckminster Fuller was published in Portfolio, 1964, n.4.

- 'Tension and compression are inseparable and coordinate functions of structural systems, but one may be at high tide aspect, while the other is at low tide."

- "Tensegrity is a type of structure with an integrity based on a balance between tension and compression components."

     
  • loading members only in pure compression or pure tension, meaning the structure will only fail if the cables yield or the rods buckle
  •  preload or tensional prestress, which allows cables to be rigid in tension
  •  mechanical stability, which allows the members to remain in tension/compression as stress on the structure increases
