ABSTRACT:
Light weight tension-compression equilibrium structures include structural units which contain a plurality of compression members in contact with each other in an interior portion of the unit and a plurality of tension members in contact with them and exerting balanced tensions on them to hold them in position with respect to each other, and to produce compressive forces in the compression members which are directed toward the point(s) of contact of the compression members in the interior of the unit, thereby strengthening the compression members and the structural units. The tension members are positioned apart such distances along the compression members less than lengths at which the compression members alone would buckle under applied compressive forces. The various structural units may be essentially planar, useful for forming walls or relatively thin supporting structures, or they may be made three-dimensional so as to be capable of serving as major load-bearing units. Various types of tension-compression equilibrium structures are illustrated, including parallelepipedal units wherein the compression members are interlocking twin tetrahedrons or such tetrahedrons internally braced by compression members or "planes" connecting the intersections of diagonals of the parallelepiped sides, or parallelepipeds made from a plurality of essentially planar tension-compression units and such structural units and pluralities of them joined together, preferably with additional tension parallelepipeds between them and exerting tension thereon, may be employed as load-bearing components of buildings, bridges, tunnels, subways towers, stanchions, dams, roadways and various other structures.
