Please forward this error screen to 164. The term was coined by Buckminster Fuller in the 1960s as a portmanteau of “tensional tensile membrane structures pdf”. The other denomination of tensegrity, floating compression, was used mainly by Kenneth Snelson. Because of these patterns, no structural member experiences a bending moment.

This can produce exceptionally rigid structures for their mass and for the cross section of the components. A conceptual building block of tensegrity is seen in the 1951 Skylon. Six cables, three at each end, hold the tower in position. The three cables connected to the bottom “define” its location. The other three cables are simply keeping it vertical. Skylon define the bottom end of its tapered pillar. A similar structure but with four compression members.

Variations such as Needle Tower involve more than three cables meeting at the end of a rod, but these can be thought of as three cables defining the position of that rod end with the additional cables simply attached to that well-defined point in space. Eleanor Hartley points out visual transparency as an important aesthetic quality of these structures. A 12m high tensegrity structure exhibit at the Science City, Kolkata. In the 1980s David Geiger designed Seoul Olympic Gymnastics Arena for the 1988 Summer Olympics.

Shorter columns or struts in compression are stronger than longer ones. This in turn led some, namely Fuller, to make claims that tensegrity structures could be scaled up to cover whole cities. On 4 October 2009, the Kurilpa Bridge opened across the Brisbane River in Queensland, Australia. A multiple-mast, cable-stay structure based on the principles of tensegrity, it is currently the world’s largest such structure. Biotensegrity, a term coined by Dr. Stephen Levin, is the application of tensegrity principles to biologic structures. A theory of tensegrity in molecular biology to explain cellular structure has been developed by Harvard physician and scientist Donald E.
