Verification of Tensegrity Properties of Kono Structure and Blur Building

Cable-bar structures are commonly used in engineering. Some of them are in special configuration named “tensegrity”. The objective of the present paper is to describe and verify two interesting examples of existing civil engineering structures called tensegrity in the literature: Kono structure and Blur building. Singular value decomposition of the compatibility matrix of truss structures is used to define two crucial features of tensegrity: existence of mechanisms and self-stress states. Eigensolution of the stiffness matrix extended on geometrical stiffness matrix allow to identify if the self -stress stabilizes the equilibrium of the structure - if the mechanisms are infinitesimal or finite.
