Abstract
Tensegrity structures are prestressed pin-jointed structures composed of struts and cables. To check stability of tensegrity structures, it's preferable to check super-stability since it is the strongest stability criterion. In this paper, we discuss the super-stability of prismatic tensegrity structures which have dihedral symmetry. In previous studies, these structures were proved to be super-stable if horizontal cables connect adjacent nodes. However, these proofs are incomplete. Therefore, we complement the proof for super-stability of symmetric prismatic tensegrity structures in this study.
