There is a phenomenal rise in construction activities in the field of civil engineering in the recent years. Major structures like building, bridges, dams, are subjected to severe loading and their performance is likely to change with time. It is therefore, necessary to check the performance of a structure through continuous monitoring. If performance deviates from the design parameter, appropriate maintenance is required. The life of the structure depends on initial strength and the post construction maintenance. It is for this reason that the necessity of structural health monitoring (SHM) is emphasized worldwide. A technique is required for structural health monitoring (SHM), which should carry out continuous monitoring of structure, as well as sensitive and cost effective. These Unique properties of direct and converse piezoelectric effects enable piezo electrio-ceramic (pzt) patch to act both as anactuator and as a sensor simultaneously. Making use of the sensing capability the of PZT patch, conductance signature of the structure can be obtained against which health monitoring of the structure can be done. Signature of the structure in healthy state is called the base line signature. It is compared with signature obtained after a time lapse, which is called secondary state conductance signature. The characteristic feature of the EMI technique is that it activates higher frequency modes of the structure.
