Abstract

Health monitoring of civil infrastructure using smart piezoceramic transducer patches K. K.-H. Tseng', C. K. Soh% A. Gupta^ & S. Bhalla^ ^ School of Civil & Structural Engineering, Nanyang Technological University, Singapore. 'Department of Civil Engineering Indian Institute of Technology, Delhi, India. Abstract In recent years, structural health monitoring has become an important requirement in Civil Engineering, especially in the densely populated areas such as many Asian cities. Various monitoring techniques have been proposed and studied. This paper will focus on the application of the piezoceramic transducer (PZT) patches on the health monitoring of civil infrastructure. The PZT patches, attached to the surface of the structure, are electrically excited, and real part of electrical admittance (conductance) is extracted as a function of the excitation frequency. An Impedance Analyzer is used to scan the patches over a certain range of frequency for the acquisit
