The cable is widely used in cable-stayed bridge, suspension bridge and other architecture structures. Obtaining the cable tension accurately is of great significance to the structural safety. Several cable tension testing methods have been proposed. Among them, the method of testing stress under the excitation of constant magnetic field is not affected by the boundary condition of the cable and avoids the influence of eddy current. Considering the structural features of the parallel wire cable, a parallel wire cable tension testing method is presented based on the principle of testing stress under the excitation of constant magnetic field and the Gauss’s law. Then an experiment setup is built. The experiment result shows that the method can be used to test the parallel wire cable tension.
