This paper proposes a new overall coordinate method (OCM) to determine the cable shape of self-anchored suspension bridges. In this method, the initial cable shape between adjacent clamps is assumed to be linear and the target cable shape is calculated by iterations based on the overall equilibrium of forces. This method is used to calculate the cable shape of the Chishui Bay Bridge in Hebei Province by MATLAB, and the results are compared with the measured data. The comparison shows that the OCM has a fast convergence speed and high accuracy. |
