STRUCTURAL HEALTH MONITORING Structural health monitoring could be phrased as the process of implementing damage detection and a characterization strategy for engineering structures. C ivil engineering structures are one of the most sought out structures in existence. Yet their existence is taken for granted, most of the time disregarding their health. In the meantime enough resources are not employed, at least periodically, to monitor their health, so that they are well maintained. The sudden collapse of such a structure, if it is of large scale, in the vicinity of a large population, its existence is crucial for the community or it is linked to the lives of the community in a greater scale, could be disastrous. Bridges, apartments, dams, oil platforms and other civil infrastructure are detrimental to the human existence. material and geometric properties of the structural system, including problems related to connectivity, which could affect As there is a risk that would pose to lives and property, moni- the performance or the functionality of the structure. toring and maintenance programmes are implemented for structures of greater importance, i.e, in socio-economic sense In that case, structural monitoring of some form at least in its or vulnerability.
