In this paper, the concept of integral-tensioning continuous cables for prestressing double-layer tensegrity (DLTG) grids is presented and its principles are discussed. A simple approach for analyzing its properties is also recommended. Among three possible integral-tension methods, the optimal is selected. The method avoids the drawbacks of the conventional prestressing methods of bar elongation, simplifies the connections between bars and cables, and produces excellent load-carrying capacity. When large grids are constructed, optimal design can be achieved.
