N2 - Stress monitoring of steel cables and tendons of structures is challenging but crucial to the evaluation of structural safety. Traditional invasive stress monitoring methods are inapplicable, or unable to measure the actual stress (not the relative variation of stress). A smart elastomagneto-electric (EME) sensor proposed by the authors for stress monitoring of steel components has shown great promise. As an innovation part of the EME sensor, the magneto-electric (ME) sensing unit, made of ME laminated composites, displays great potential to be used to design the novel sensor with significant advantages such as small size, large magnetic conversion coefficient, fast response, high magnetic-sensitivity, and low cost. In this work, the intelligent stress monitoring for steel cables in the Second Jiaojiang Bridge and prestressing tendons in the Quanzhou Bay Bridge of China using the developed EME sensory system is introduced, including the full-scale experiment, factory calibration, and in-situ verification for engineering application.
