Outline of Final Research Achievements

This research is concerned with analysis and design of tensegrity structures. We aim to establish a systematic and unified way to design tensegrity structures. To fulfil an allotted space by tensegrity structures, we proposed a general-purpose tensegrity assembly (tensegrity sheet) composed of repetition of simple fundamental units. From the sheet, we can produce shell-type structures such as tori, cylinders, paraboloids, spheres, ellipsoids, etc., by specifying the node locations and boundary conditions. For the design and analysis of tensegrity structures, we proposed a mathematical framework, from a network perspective, that can easily handle the change of structural configurations (add/delete/exchange members, change connection/shape, etc.). Some of the design and analysis problems such as minimal mass design and dynamical analysis are discussed under this mathematical formulation.
