Tensegrity

Tensegrity, a portmanteau of “tensional integrity,” describes a structural system composed of continuous tension and discontinuous compression. In this architectural marvel, compression members, like struts, are suspended within a network of tensile elements, such as cables or wires. The tension pulls the struts together, preventing them from separating, while the struts resist the pulling force, creating a stable, self-supporting structure. This interplay of forces allows tensegrity structures to be surprisingly lightweight, strong, and adaptable to varying loads, offering a unique approach to design and engineering principles. The resulting forms can be extraordinarily complex and aesthetically pleasing.

Tensegrity meaning with examples

• The artist employed tensegrity principles to create a stunning kinetic sculpture. The piece seemed to defy gravity, with struts floating impossibly within a web of steel cables, constantly shifting and reforming. This display emphasized the balance of tension and compression.
• Engineers are exploring tensegrity as a viable solution for lightweight bridge construction. The design offers improved load-bearing capacity and stability due to the interplay of tensile and compressive forces, minimizing material use.
• The geodesic dome incorporated tensegrity principles, using tension to keep its members together to create a strong exterior that can withstand harsh weather conditions, and creating an impressive structure.
• A fascinating example is the self-erecting tensegrity tent design, a structure that can be assembled quickly without complex tools. Tension from the cables pre-loads the struts, allowing the tent to pop into its three dimensional form.
