Earthquakes and Health Monitoring of Civil Structures

---

Damages due to catastrophic earthquakes are huge. Over a million and half people
have been killed during the most catastrophic ten earthquakes that have occurred
since 1900. Still, the number of victims and material damage due to earthquakes
has permanently been growing although, according to statistics, the number of
catastrophic earthquakes per annum is constant. For example, the Haiti earthquake
with magnitude M = 7 that occurred in 2010 took 316,000 human lives, destroyed
and damaged 97,294 and 188,383 houses, respectively. It was the deadliest earthquake
that has ever occurred. Such an increase of number of victims and damages
has mostly been due to intense urbanization resulting in an increased density of
population in the seismically active belts of the Earth.

Since the seismic hazard cannot be reduced, the seismic risk related to civil
structures can be decreased in a number of ways. One of the basic measures of
reduction of such risk is permanent development of new methods of analysis of
structures for the effect of earthquakes as well as constant improvement of seismic
design regulations in seismic regions. The technique of health monitoring of
structures (HMS) that has lately been applied in civil structures is also one of the
methods contributing to reduction of seismic risk.

HMS is mostly applied in aeronautics and mechanical engineering. The application
of HMS in civil structures still lags behind its application in the above
mentioned disciplines. The earliest application of this technique in structural
engineering is traced back to the seventies of the last century when mass measurement
of dynamic characteristics of full-size structures begun by use of the ambient
and force vibration techniques. With the invention of the first strong motion instruments
and parallel to their installation on ground, a certain number of buildings
were instrumented for the purpose of measuring their dynamic response with the
triggering of these instruments by stronger earthquakes. However, all these measurements
are associated with a certain time period. Continuous real-time measurements
of behavior of structures has been enabled later, as a result of the development of fast
data acquisition systems and real-time transmitting of data to centres for monitoring
of structures. Most of this book is dedicated to modern real-time HMS.
