ABSTRACT:
A multi-conic shell and a process of creating multi-conic shells from flat materials which are bent and thereby forced into the configuration of continuous regions from oppositely oriented, tangential cones to create variably configured building structures and variably configured lightweight structural panels. The process of creating multi-conic shells from connecting cone segments corresponding to a theoretical array of regular (opening downward) and inverted (opening upward) cones provides an unlimited number of variations for the design of building structures and the design of structural panels. Such multi-conic structures achieve excellent strength to weight ratios by distributing loads into tension and corresponding tetrahedron structures which propogate throughout the shell. One embodiment is a building structure wherein a number of generally two-dimensional panels constructed of plywood or other flat materials are raised and forced into multi-conic surface positions by the use of winches, or other mechanical devices thus creating one or more multi-conic shells. Another embodiment is a structural panel manufactured by bending flat panels or stamping, vacuum forming, or casting materials into multi-conic shells which attach to one or more panel surfaces to create a sandwich type structural panel.
