    • 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.
    • 轻量级张力 - 压缩平衡结构包括结构单元,其包含在单元的内部部分中彼此接触的多个压缩构件和与它们接触的多个张力构件,并且在它们之间施加平衡的张力以将它们保持在适当位置 并且在压缩构件中产生压缩构件的压缩力,该压缩构件指向单元内部的压缩构件的接触点,从而加强压缩构件和结构单元。 张紧构件沿着压缩构件被定位成离开这样的距离,小于在施加的压缩力下单独压缩构件将弯曲的长度。 各种结构单元可以是基本上是平面的,可用于形成壁或相对薄的支撑结构,或者它们可以被制成三维的,以便能够用作主要承载单元。 示出了各种类型的张力 - 压缩平衡结构,包括平行六面体单元,其中压缩构件是互锁的双四面体或由压缩构件内部支撑的四面体或连接平行六面体侧面的对角线的交叉点的“平面”或由多个平行六面体制成的平行六面体 基本上平面的拉伸压缩单元,并且这种结构单元和多个它们连接在一起,优选地在它们之间具有附加的拉力平行六面体并且在其之间施加张力,可以用作建筑物,桥梁,隧道,地铁塔,支柱, 水坝,道路和各种其他结构。
