Long-Term Structural Performance Monitoring of Two Highway Bridges. Phase I: Instrumentation
In this project, sensor systems for long-term structural performance monitoring have been installed on two new highway bridges in Orange County, California: the Jamboree Road Overcrossing and the West Street On-Ramp. They include accelerometers, strain gauges, pressure sensors, displacement sensors, installed or embedded at strategic locations of both super- and sub-structures. Data recorders and power supplies have also been installed at the bridge sites. Although the major focus of this Phase 1 project in on the sensor installation, preliminary vibration measurement and data analysis have been performed on these two instrumented bridges. On the Jamboree Road Overcrossing, Ambient vibration data have been collected, base on which natural frequencies and mode shapes have been extracted using various methods and compared with those obtained by the preliminary finite element analysis. On the West Street On-Ramp, braking and bumping vibration tests have been carried out using a water truck in addition to ambient vibration tests. Natural frequencies and mode shapes have been derived and the results by the breaking and bumping vibration tests have been compared.
