Tensegrity is a structural design principle that applies to a structure which can be entirely stabilised by an internal pre-stress. This pre-stress is created by a discontinuous set of compression elements being opposed and balanced by a continuous tensile force.

Inside the net of continuous tension, typically bars or struts (the compressed elements), are free from touching, and typically cables or tendons (the pre-stressed tensioned members) spatially delineate the system.

The pioneering architect Buckminster Fuller coined the term tensegrity in the 1960s, as a combination of ‘tensional integrity’. However, the American sculptor Kenneth Snelson has long-claimed that Fuller took credit for his original idea of ‘floating compression’. Snelson defines tensegrity as follows:

‘Tensegrity describes a closed structural system composed of a set of three or more elongate compression struts within a network of tension tendons, the combined parts mutually supportive in such a way that the struts do not touch one another, but press outwardly against nodal points in the tension network to form a firm, triangulated, prestressed, tension and compression unit.’

It is the combination of a few simple design patterns that define tensegrity structures, and help to produce exceptionally rigid structures made up of members that do not experience a bending moment. Some of these design patterns are as follows:

* Members are loaded only in pure compression or pure tension. This means the structure will fail only if cables yield or rods buckle.
* Cables are made rigid in tension via preload or tensional prestress.
* With an increase in stress on the structure, the members remain in tension/compression through mechanical stability.

A famous example of a tensegrity structure was the Skylon, exhibited at the Festival of Britain in 1951 [see top image]. The tower was held in position by six cables, three of which were at the bottom and determined its location, while the other three were at the top and maintained its verticality.

One of the first uses of tensegrity in architecture was Spodek, an entertainment venue in Poland, designed by architects Maciej Gintowt and Maciej Krasiski in the 1960s. The roof was an inclined surface, the circumference of which was held up by a system of cables.
