Principles of Potential Energy for Cable Networks
A cable network is a structure realized as an assembly of cable members. One remarkable example that can be regarded as a “pure” cable network, i.e., a structure consisting of only cable members, is the roof of the Arena for the Munich Olympics in 1972 . Besides these pure cable networks, it is often that a cable member is employed together with other structural elements, particularly in large-span civil engineering structures, because its light-weight property and its flexible realizability of curved surface given by designers. Such a class of structures, called cable-supported structure, includes cable-suspended roofs, cable domes, cable-supported membranes, and tensegrity structures; see, e.g., Bradshaw-Campbell-Gargari-MirmiranTripeny , Harris-Li , Lewis , Motro , Narayanan , Pellegrino , and Skelton-de Olivira .
