Abstract
Monitoring of cable stress of in-service structures is challenging but crucial to the evaluation of structural safety. A smart Elasto-Magneto-Electric (EME) sensor proposed by the authors for stress monitoring of steel components displays great superiorities over the traditional Elasto-Magnetic (EM) sensors. In this paper, the application of the developed EME sensory system on the cable force monitoring of the Second Jiaojiang Bridge in China is presented. The capacity of this EME sensory system in monitoring cable stress was firstly verified using full-scale experiment. Then the factory calibration and in-situ verification for engineering applications were successively carried out. The research results demonstrate that the proposed EME sensor is feasible for stress monitoring of steel cables with high sensitivity, fast response, and ease of installation. Long-term on-line monitoring of the cable forces is in progress and the typical monitoring data are presented and discussed.
