In past research, elasto-plastic behavior of structure with cables under earthquake load and the snow load was reported. Although specific stress-strain relationship of cables was assumed in such research, reliable data is currently available in limited diameter and wire constitution. In addition, the elongation distribution in the tensile test along overall length has not been reported. The goal in this research is to grasp characteristics until ultimate state (fracture), and to propose reliable stress-strain relationship model generally adaptable of structural cables.
