Structural health monitoring (SHM) is a process for evaluation of the structural safety status from structural response measurements. The ultimate goal is to develop an economical and non-destructive system for the earliest possible detection of damage. It has been attracting much attention in the past two decades. A tremendous amount of efforts have been dedicated in this area [15,18,19,25,51,52,68,69,77,101,103,106,138,142,143,149,160,168,174,185], [186,195,201,204,228,238,244,246,261,267,268,281,282]. Comprehensive literature reviews on the development of SHM can be found in Doebling et al. [69] and Sohn et al. [247] and there were also a number of workshops, [1,44,187], for example, and special issues of journals, e.g.. Journal of Engineering Mechanics in July 2000 [90] and January 2004 [26] and Computer-Aided Civil and Infrastructure Engineering in January 2001 [278] and May 2006 [22].

A general procedure for structural health monitoring that includes both damage detection and reliability assessment of a structure subject to seismic excitation is briefly illustrated and applied to an example case. The procedure is formulated in a unified probabilistic framework that can take into account any kind of uncertainty involved in the various phases of the analysis. 

Sensory structures however, are able to detect and monitor deformations, deflections or even structural conditions and properties (e. g. the growth of damages) via integrated sensors. In the case of a critical condition or property an output of information about the actual condition or just a warning will be generated. This kind of condition monitoring (CM) is also called structural health monitoring (SHM).

In recent years, Structural Health Monitoring (SHM) of engineering structures has become an important area of research. This is a broad term which by large also deals with the online detection and identification of structural damage and therefore holds a critical significance for the case of large-scale civil structures where a failure incidence is connected not only to high cost losses but potentially to human loss in the worst-case scenario.
