ABSTRACT:
A stable structure consisting of tubular components and supporting cables or other tensory elements, where the supporting cables, used in pairs, are introduced via pairs of perforations which are positioned excentrically at the respective ends of two predefined chords of a section of the tubular component, so that the tensioning of the cables transforms what is initially an unstable structure into a completely stable one whose form is dependent upon the relative lengths of the two cables in each pair of cables.
