wonderful tensegrity structures

Tensegrity structures are visually stunning and their combination with computer enhanced structures is creating renewed interest for architectural applications.

Buckminster Fuller coined the term tensegrity when he saw sculptures by Kenneth Snelson and realized that rigid component geodesics were a special case of perfectly balanced compression and tension. Tensegrity refers to structures where compression members (rods) are only connected to each other by tension members (cables). The end result is that the structures appear to float in air.

Despite the fact that tensegrity structures are fantastically efficient, few have been built since they tend to have a single point of failure and need adjustment. Recently however, schemes which combine the intelligence of computing and tensegrity structures have lead to proposals of very large scale structures including sky scrapers.

Im struggling to see exactly how this proposal is a tensegrity structure, but Ill take their word on it, since, in any case its rather beautiful.<p /><p />A series of cable tensioned hoops run the length of the bridge with a woven kevlar membrane, enclosing them.<p /><p />
Although Buckminster Fuller popularized tensegrity structures, it was as a result o seeing Kenneth Snelsons tensegrity sculptures. Shown here is a piece inside the Mies Van der Rohe Berlin Modern Art Gallery.<p /><p />Snelsons website, linked here, is a must for all tensegrity fans.
For some reason, three strut tensegrity based tables seem to cost a fortune, they can look great, however and it might be worth making your own.
This page analyses bio-mechanical problems from the viewpoint of representing them as tensegrity structures.
Filamentosa is another project by ORAMBRA, envisioning actuated tensegrity scaffolds surrounding a fixed core, to provide ultra lightweight structural systems for skyscrapers.
Metalsmith, Arnold Patrick Martin produced this elaborate Tensegrity ring. something to give to that special architect in your life.
This is an obvious (in retrospect) and great use of the tensegrity concept. The compression members are fluorescent lamps, which are connected by tension wire electrical cabling.
One of the classic tensegrity designs. The size of the overlap between compression members increases the triangular area where a pin joint would be in a regular geodesic.
Linked to here is Fullers essay on tensegrity.
A really nice little model built at the University of Arizona, where the struts in a tensegrity dome are bent, to form simple ,multiple element, trusses for the compression elements.<p /><p />The end result is very appealing, visually.
The Bureau For Responsive Architecture (ORAMBRA) have some fantastic active tensegrity designs including videos, on their website, linked to here.
The simplest way to build your own tensegrity structure is from drinking straws, rubber bands and paper clips, joining struts by looping through the elastic bands, rather like a collection of interlocked violin bows.<p /><p />This allows for adjustable length connections, by sliding along the bands. Unfortunately a structure such as this will only last around a year, as the rubber vulcanizes.
The Biot project was an attempt to build a robot based upon a tensegrity structure.
