tensegrity

Tensegrity structures belong to a special category of cable structures. They are defined as systems composed of compression components (struts) inside of a continuum of tension components (cables) in a stable self-stressed state (equilibrium). They are lightweight structures offering higher resistance than other systems of the same weight. Another advantage is their modularity; stable modules can be joined together creating larger tensegrity systems.

From an engineering point of view, the construction of the Tank Street Bridge is a civil engineering achievement. Tensegrity structures are highly complex systems with non-linear behavior. Therefore, the analysis of these structures demands complex computational methods. Additionally, previous tensegrity constructions such as the Rostock tower (Germany) revealed a necessity for high precision. It is also important to mention that there are no widely accepted guidelines for the construction of this kind of structures.

The resulting tensegrity bridge is a network of cables held apart by numerous struts recalling the ropes and spars of sailing ships and boats. Seen from the rivers, struts seem to float over the bridge. They remind sculptures made by the American artist Kenneth Snelson (see “Easy Landing”). Additionally, due to its tensegrity system the bridge offers high transparency with great views over the river to pedestrians. During the night, the bridge will be full of colors. LED lights are chosen to highlight the masts with pastel colors creating a levitating illusion for pedestrians. Different colors will be applied based on the chosen theme creating a contemporary sensation.
