Sensors are used for civil infrastructure performance assessment and health monitoring, and have evolved significantly through developments in materials and methodologies. Volume I provides an overview of sensor hardware and its use in data collection. The first chapters provide an introduction to sensing for structural performance assessment and health monitoring, and an overview of commonly used sensors and their data acquisition systems. Further chapters address different types of sensor including piezoelectric transducers, fiber optic sensors, acoustic emission sensors, and electromagnetic sensors, and the use of these sensors for assessing and monitoring civil infrastructures. Developments in technologies applied to civil infrastructure performance assessment are also discussed, including radar technology, micro-electro-mechanical systems (MEMS) and nanotechnology. -- Performance assessment and health monitoring of civil infrastructures has the potential to increase public safety while decreasing maintenance costs. Typically, sensors are strategically placed in a structure to measure and record data and to draw conclusions about the state of a structure. Volume 2 takes the reader through sensor data management and analytical techniques for fault detection and localization. It will look at prognosis and life-cycle assessment. The majority of the chapters are case studies in assessing structures such as bridges, buildings, super-tall towers, dams, tunnels, wi.
