Flexural tensegrity: Field applications

Claudio Boni , Gianni Royer-Carfagni

Abstract. Flexural tensegrities represent a class of structural elements composed of segments in unilateral contact along properly-designed pitch profiles and held together by pre-tensioned cables. The cables are constrained in cavities inside the segments and can move within them, while the segments can roll one another along the pitch surfaces, thus straining the cables to an amount dictated by the shape of the contact profiles, and affecting the energy landscape of the assembly. A range of possible field applications, yet to be fully explored, is here presented.
