Sensing Issues in Civil Structural Health Monitoring


Structural health monitoring (SHM) is emerging as an important element in managing the public works infrastructure systems such as bridges,

tunnels, buildings, dams, and power plants.





PREFACE

To a greater extent,

infrastructure has become more reliant on SHM for myriads of reasons that include increased number of aging structures, bold concepts in design of

innovative structures, use of new materials, increased costs associated with the maintenance, safety, and security as well as the need for effective post disaster condition surveys. A successful civil structural health-monitoring

(CSHM) program involves selection and placement of sensors suitable for measurement of key parameters that influence the performance and health of

the structural system. Survey of literature reveals development of a number of conventional and novel sensors for this purpose including optical fibers, MEMS, PZT and magnetic based sensors.
