Abstract

As structural materials, cement-matrix composites have received much attention in terms of their mechanical properties. The ability to provide non-structural functions allows a structural material to be multifunctional, thus saving cost and enhancing durability. The ambient vibrations created by the civil structure (bridge) are converted into electrical signal by the property of the micro planar piezo-electric sensor element. The use of the piezo- patches as transmitting and sensing element the life cycle of civil infrastructure such as bridges and buildings can be monitored. The design of the wireless sensor network and the concrete matrix is also aimed at applications of structural health monitoring. The practical applicability of the sensor network is increased through utilization of computational intelligence and support of signal generation capabilities, based on the method of modal strain energy. The automation tasks in this paper include automation of the modal identification through ambient vibrations, classification of the acquired mode shapes, and automatic evaluation of the structural health and embedded ultrasonic transducers for concrete property diagnosis. This review is thus based on using the energy efficiently by conserving the electricity and increasing the life cycle of the civil structures by the proper proportion of the composites and monitoring it.
