Structural health monitoring (SHM) is a process aimed at providing
accurate and in-time information concerning structural health condition
and performance. The information obtained from monitoring is generally
used to increase the safety, plan and design maintenance activities,
verify hypotheses, reduce uncertainty, and to widen the knowledge
concerning the structure being monitored. How to realize the effective
monitoring is what the researchers devoted to in the past and recent
studies. This book, therefore, is focused on the research of critical
phenomena in different size-scaled structures, from earth-scale,
macro-scale to micro-scale. By analyzing the energy emission from their
critical processes, some useful information or suggestion is extracted
and to be provided in SHM. Three different forms of energies, acoustic
emission (AE), electromagnetic emission (EM) and neutron emission (NE),
are selected to be studied in our research. The book is useful for the
civil engineers, graduate students, researchers, practitioners,
consultants, contractors, infrastructure managers interested in the
application of new technologies to structural health monitoring.
