A tensegrity system can be defined as a balance of compression elements (usually bars) and tensile elements that complete a system of rigid partials efforts that secures a total.
flexibility, stability, sustainability
As for the dilemma in order to serve this type of system, you can imagine applied
furniture, roof types, megastructures. The structural aspect is suitable for functions where the symmetry can be of help: repetitions of rooms, modules, large decks.

Among the papers presented, draw attention to column structures, according to the same language, share an identity with braid or braiding. In tensegrity structures complete triangulation, the network voltage is very important, deciding whether the structure is firm or flaccid. Only the cross with his two props (and four members of tension), and the prism of three-way primary between these figures have total triangulation (bottom). The square, pentagon and hexagon do not. These can be stabilized with additional lines, but the additional lines will necessarily be selective in the directions that distort the picture.
solid, three-dimensional bars can be interpreted as edges, taken to be the geometric generation. The flexibility inherent in tensegrity systems is itself helical, and the whole tower structure bends slightly when compressed from top to bottom. Otherwise, if the cumulative bending is the goal, then all modules should be in a helical direction.
Around the relationship with folds, this column folded paper (above) simulates the geometry of a tensegrity column of three ways. The type 1 is red triangles, and type 2 is green. Thus the concavity and convexity in the folds of the paper carried a close relationship tensegrity tension and compression forces model.
The text defines three kinds of power lines: lines " edge "(green), which define the sides of each module (in most cases the edges have less stress), line" stretching "or tow ( blue), strokes, pulling the modules to each other, and lines "sling" (red), who fail modules, such as chains, or bands. In the forms of kite marks ("Kite frame"), meanwhile, are produced from crosses buildings and tension rigid perimeter. When one of these edges are replaced by another element, rigid or modular, there are multiple variations of this classification. Replace a rod or stiffener with an X-module (module on the cross), and produces a variant. This new combination of two modules in cross represents the first stage of construction process, which can be extended indefinitely. Each quadrant open any module and provides a place to connect other.

I will try to advance in the understanding of such systems and their practical application.
