Online Bridge Crack Monitoring with Smart Film

Blog Article

Smart film crack monitoring method, which can be used for detecting initiation, length, width, shape, location, and propagation of cracks on real bridges, is proposed.Firstly, the fabrication of the smart film is developed.Then the feasibility of the method is analyzed and verified Cable Suspension by the mechanical sensing character of the smart film under the two conditions of normal strain and crack initiation.Meanwhile, the coupling interference between parallel enameled 89% XDARK CHOC BAR wires of the smart film is discussed, and then low-frequency detecting signal and the custom communication protocol are used to decrease interference.On this basis, crack monitoring system with smart film is designed, where the collected crack data is sent to the remote monitoring center and the cracks are simulated and recurred.

Finally, the monitoring system is applied to six bridges, and the effects are discussed.
