  • Patent number: 4442639
    Abstract: A structure and method for producing such a structure of a unique design is disclosed. The structure produced by the features and techniques of this invention comprise a base (16) which is typically supported by the earth (18). The base (16) supports a vertical core structure (14) which extends from the base to a top end. A tension ring (24) is fixedly attached to the top end of the core structure (14). In addition, a compression ring (22) is fixedly attached to the core structure (14). A multiplicity of curved meridian members (26), (28), (30) and (32), extend between the tension ring (24), and the compression ring (22) are of a single selected shape and are circumferentially shaped around the tension ring (24) and the compression ring (22). A multiplicity of radial members (62 through 68) extend horizontal between the core structure (14) and the curved meridian members (26 through 32) and provide structural support for floors and ceilings separating various building levels.
