Bridges represent significant investments in the U.S. highway transportation network, and a reliable, low cost bridge monitoring and inspection system is a critical need. To address this, IAI and its collaborators from Penn State University, Z-DAC, and Hardesty & Hanover, have been awarded a supplement to a follow-on contract entitled, “A Novel Multi-Sensor Wireless Network for Bridge Structural Health Monitoring.” A wireless multi-sensor network for Structural Health Monitoring (SHM) of steel bridges and concrete pavements is being currently developed, which includes acoustic emission sensors, ultrasonic guided wave sensors and strain gage sensors, and provides early warnings of critical structural problems through cooperative network sensor data processing and diagnosis. The sensor data are collected, processed, and then transferred to a remote maintenance office via a commercial Global System for Mobile Communications (GSM) cellular network. Field operation validation test of the developed prototype will be conducted on real bridge structures from Florida and Maryland. Tasks will include field instrumentation and testing of the prototype sensor system, conducting a live load test for data collection, collecting long-term sensor data for the bridges, and developing a software tool for data collection, management and processing. The end product will be weather proof, self-sufficient, and easy to install and maintain. It will include a comprehensive, automated data collection and management software tool that can collect sensor data remotely and analyze the data for damage diagnosis. The wireless multi-sensor network will also be adapted for embedded concrete quality control and condition monitoring. The current efforts will help to mature and commercialize the prototype bridge health monitoring system, which can be readily marketed to state and local agencies, and bridge owners.
