Wireless Sensing and Embedded Monitoring Algorithm for Damage Diagnosis in PSC Girders
In this study, a hybrid health monitoring technique that combines wireless sensing and embedded monitoring algorithms is proposed to realize the diagnosis of damage in PSC girder bridges. Firstly, a hybrid damage monitoring system that can alarm damage occurrence and classify damage-types is designed for PSC girder bridges. Secondly, smart sensor nodes that have wireless, stand-alone, sensing and monitoring capacities of acceleration and impedance are developed for hybrid health monitoring of the structures. Finally, the performance of the smart sensor nodes is evaluated using a laboratory-scale PSC girder bridge model for which acceleration and impedance signals were measured for prestress-loss and stiffness-loss cases.
