Long-Term Structural Performance Monitoring of Bridges. Hardware Maintenance and Long-Term Data Collection Analysis
In this project a description of the maintenance of the sensor monitoring systems installed on three California highway bridges is presented. The monitoring systems consist of accelerometers, strain gauges, pressure sensors, and displacement sensors which were installed on three highway bridges over the last decade: the Jamboree Rd. Overcrossing, the West St. On-Ramp, and the Fairview Rd. Overcrossing. Based on the measured sensor data under traffic and seismic excitations, the research team established baseline models of the bridges, and developed methodologies for structural health monitoring and damage assessment. The measured sensor data have provided better understanding of behaviors of highway bridges under traffic and seismic structural performance database. In total, 15 journal papers resulting from this Caltrans-sponsored project were published and 1 more is being evaluated for possible publication. In order to improve the efficiency and reliability of data acquisition, the research team has repaired and maintained the existing data acquisition systems. Specifically, the following major tasks has been carried out: (1) maintenance of the sensors, data loggers, and power suppliers; (2) establishment of a reliable Internet-based remote access to the data loggers; (3) development of software for remote control of the data loggers through Internet; (4) data collection of the three instrumented bridges under controlled and uncontrolled traffic excitations, as well as seismic excitations; and (5) data analysis and baseline updating by taking into consideration of influence of weather and traffic.
