Tensegéris

Tensegrity, also spelled tensegrity, is a structural principle that describes a stable, lightweight, and flexible structure composed of isolated compression elements (struts) and continuous tension elements (ties). The term was coined by Buckminster Fuller in the 1950s, derived from the words "tensional integrity." Tensegrity structures are characterized by their ability to maintain stability and shape without the need for external bracing or rigid connections between elements.

The fundamental principle of tensegrity is that the tension in the ties must be sufficient to prevent the struts from buckling or collapsing under compression. This is achieved by carefully balancing the forces and ensuring that the structure is in a state of prestress, where the ties are initially tightened to a specific tension level. This prestressing allows the structure to resist external loads and deformations while maintaining its overall shape and stability.

Tensegrity structures have been employed in various applications, including architecture, engineering, and art. In architecture, tensegrity principles have been used to design lightweight and flexible buildings, such as the Geodesic Dome by Buckminster Fuller. In engineering, tensegrity structures have been explored for their potential in creating adaptive and resilient infrastructure, such as bridges and towers. In art, tensegrity structures have been used to create dynamic and interactive installations that challenge traditional notions of form and stability.

Despite their potential, tensegrity structures face challenges related to their complexity, stability, and scalability. Researchers and engineers continue to study and develop new tensegrity structures to overcome these challenges and unlock their full potential in various applications.
