The field of civil engineering is radically changing based on the emergence of sensing, data and modes of automation previously unimaginable. One of the most successful advancements has been wireless sensors that can be used to collect structural response data with high nodal density and low installation costs. As wireless sensors proliferate across our industry, the ability to collect data related to the performance of infrastructure is shedding new light on how infrastructure systems perform including how they deteriorate over time. A secondary benefit of wireless telemetry is their seamless integration with Internet-based computing resources which is rapidly transforming monitored civil infrastructure into cyber-physical systems (CPS) capable of automating their data collection in response to their operation. This presentation describes the development of wireless sensors for structural health monitoring (SHM) including an overview of experiences with long-term field deployment of wireless SHM systems on highway bridges. The presentation also describes expansion of SHM system functionality by integrating them into a broader CPS architecture. The presentation describes the deployment of a CPS architecture along a 20-mile segment of I-275 in southeast Michigan that has been designed to track heavy trucks loading a network of monitored bridges. An emphasis is placed on the use of long-term response data generated by the CPS architecture to transform the decision making of the bridge owner, leading to more efficient asset management.
