ABSTRACT:
A compression-tension unit for use in a tensile-integrity structure wherein end portions of an elastic cord are passed through slots in the opposite ends of a strut with a stretched intermediate cord portion therebetween, and opposite tips of the cord are held in lateral holes in the strut end portions adjacent the slots, there being a choice of such lateral holes spaced longitudinally apart at each strut end portion so that the degree of stretch in the intermediate cord portion can be varied.
