| Abstract: | The specific fiber Bragg grating(FBG) strain sensors and FBG temperature sensors were fixed on the outer steel wires of cable pipe so that the smart bridge cable was realized successfully which can monitor on line cable force and temperature in real time.However,the reliability of smart bridge cable with built in sensor should be researched further. By simulating the bearing alternating stress load on the smart cable during operation period and based on the fatigue performance requirements for the bridge cable in National Standard GB/T18365 2001,the fatigue property of the smart bridge cable integrated with FBG sensors was tested.The results showed that the smart bridge cable met the requirements of fatigue and static load. The sensing signal of the built in FBG sensor was still effective after and during 2 million fatigue cycle times of smart bridge cable. |
