Some Famous Tenspression (tensegrity) Building

The Kurilpa Bridge is a pedestrian and bicycle bridge over the Brisbane River in Brisbane, Queensland, Australia. Kurilpa Bridge is the world’s largest tensegrity bridge.The bridge structure comprises 18 structural steel bridge decks, 20 structural steel masts and 16 horizontal spars or in layman's terms horizontal masts. 72 precast concrete deck slabs sit on the main bridge deck and are secured to the steel structure and together by in-situ concrete stitch pours. The complex cabling system comprises 80 main galvanised spiral strand cables and 252 tensegrity cables that are made from superduplex stainless steel.


This is a 18-meter-high sculptures based on tensegrity concepts:Needle Tower (1968).
This very tall abstract sculpture depicts a tapering tower that is made of aluminum and stainless steel. Pipes of varying lengths and dimensions are strung together with a single piece of stainless steel.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.
