Abstract:
Authors derived a set of differential equations for real suspended cables according to the force conditions. Then, authors calculated the suspended curve-shape of cables by using numerical method under different conditions and compared them with the calculation results of catenarian theory. Results show that suspended curve-shape of cable is related to flexural rigidity and unstressed length of cable in determined physical characteristic, when unstressed length of cable is longer, the suspended curve-shape of cable and the catenarian curve are more similar. The calculation result can provide reference for building accurate calculation model of real cable structures.
