In this researdh, the tensile experiment to focus on the behavior of the wrapping wire and the berKbng experiment to focus on the influenoe which the wraaping tension exerts on the behavior of the parallel wire cable are conducted The specimens used are three parallel wire cables constituted of PWS253 is 5.0mm in dian filler wires, and low carbon steel wire as the wrapping wire. The specimens were wrappad by wrapping tension of 0.29, 0.4, and 0.57kN respectively. The cable tension was set to obtain the sane geonelric stiffness as the main cable in the actual suspension bridges The following results are obtained from this study. The bending stiffness of the vvrapped parallel wire able is controlled by the cable tension, warpping tension, and the bending angle of the cable. Moreover, the secondary stress of the wrapped parallel wine cable is by sliding between the wires.
