Development and Implementation of a Remote Real-time Monitoring System for Cable Force of Tianjin Yonghe Cable-stayed Bridge

Bridge cables are used as critical structural components for cable-stayed bridges. It is essential to identify and monitoring the cable force of cable-stayed bridges in real time and continuously. In this paper, the design of a remote real-time cable force monitoring system including both hardware and software components are realized and the specifications of the system are also presented. The system was implemented in the Tianjin Yonghe cable-stayed bridge located in Tianjin, China, to remotely monitor the cable fore of the bridge and provide the condition assessment of the cables to the users via Internet. Experiences with this system demonstrate how effective low cost system provides a tremendous cost savings in terms of travel time, maintenance, and repair costs. This paper will also discuss the monitoring system and provides a preliminary analysis based on the data acquired from this system.
