Structural Health Monitoring (SHM) is the integration of a system of sensors, model validation, system identification, monitoring strategies, data mining, data management and interpretation of the data for decision-making purposes. The term civionics has been coined to denote the integration of civil structures with electrophotonic sensors for the purpose of determining the health of the structures.

The use of SHM requires the integration of several different disciplines, including civil engineering, electrical engineering and physics. When experts in different fields come together for an SHM project, communication can be difficult, each expert not necessarily understanding the basics of the others’ fields of expertise. This book aims to fill the interdisciplinary gap for engineers in relation to the SHM of bridges, providing the necessary information in one volume.

Expert international authors contribute chapters on the aspects of SHM that address performance monitoring for bridges. The performance of structures is determined from measurements of strain, load, temperature, deformation, vibration and environmental conditions using various forms of instrumentation. In addition, the monitored performance is complemented with theoretical modelling to determine load capacity ratings and to estimate the remaining service life. The book addresses the integration of traditional visual assessment and field/laboratory destructive testing programs with state-of-the-art internal condition assessment through non-destructive evaluation of concrete, steel and wood structures. The chapters are based on original basic research as well as on novel applications of sensors to civil infrastructure systems, with a focus on highway and railway bridges.
