| Outline of Final Research Achievements |
Tenserity is composed of struts in compression and cables in tension. A tensegrity can maintain its stability with less members than a conventional truss. The special properties of tensegrities in mechanics as well as in mathematics have been separately studied in structural mechanics and applied mechanics. And they have found applications in many different disciplines nowadays. In this study, we have clarified the super-stability conditions for some tensegrities with high level of (polyhedral) symmetries; moreover, we have developed some techniques making use of topology optimization to find the possible topology guaranteeing super-stability of a tensegrity; furthermore, we have tried to summarize these results in a more general framework based on combinatorial rigidity theory.
