The cable structure has been widely used as structural elements for a large span structure. However, there is a lack of detailed design data, and based on the data of large-diameter cables currently used for bridges, the authors are constructing a design method for intermediate joints to be joined using small-diameter cables. The joint metal fitting becomes large. In addition, there is no experimental value for the spring constant in the lateral direction of the cable in the current design method. In this report, the authors experimentally grasp the value of spring constant in the lateral direction of cable and effect of lateral pressure on breaking load.
