In the recent past, many smart materials based structural health monitoring (SHM) technique has attracted academics and industries to carry out the health inspection of bridges, underground structures and many civil infrastructures. The applications of smart material such as piezoelectric transducer (PZT), due to its ability to sense the defects of engineering structures when actuated under the presence of electric field are improving rapidly. This final year project describes one such advancement which can enhance the PZT based SHM for electromechanical impedance (EMI) technique to monitor the structural performance of engineered cementitious composites (ECC) specimens. The principal methodology is to record the admittance signatures obtained from the actuation of PZT transducer which is attached to the ECC specimens. Any qualitative changes in the admittance signatures imply the subsequent disturbances in the specimens. This research demonstrates the adoptions of a commonly used surface bonded PZT transducer with a newly developed nut-bolt-PZT assembly. Experimental signatures are recorded from both surface bonded and nut-bolt-PZT assemblies. In addition, the resulted admittance signatures are compared to the numerically simulated signatures.
