Structural-Infrastructure Health Monitoring

This chapter provides an overview of a Cyber Physical System (CPS) for civil infrastructural monitoring. Specifically, a prototype design and implementation of a cyber infrastructure framework for the monitoring of bridges along a highway corridor is described. The cyber infrastructure framework includes two basic components, namely a sensing and monitoring component and a cloud-based computational platform. The sensing and monitoring components includes a network of sensors and cameras instrumented along the highway corridor to capture vehicle loads and bridge responses. The computational tasks involve information modeling, database management and web services for supporting SHM applications. Selected examples are provided to illustrate the utilization of the CPS for assessing the fundamental behaviors of bridge structures. Additionally, the CPS provides a platform that enables research and development of new and innovative data-driven approaches for SHM.
