Recent advances in structural health monitoring (SHM) techniques, particularly the electro-mechanical impedance (EMI) methodology, had proven to be a successful, time-saving, and simple non-destructive evaluation process (NDE). The assessment of structural performance in terms of serviceability, ultimate limit states, durability, and catastrophic failure has long been a major concern. Early diagnosis of structural faults is critical for condition monitoring of any structure, especially after a natural disaster like an earthquake. The sensing network, data processing and analysis, damage assessment, and decision-making are all critical components of an SHM approach. The structural health monitoring technique used in this study is based on Electro-mechanical Impedance (EMI) which analyses the signature of vibrations of the target member or structural system. For a long time, this has been considered by many researchers globally. A key aspect of the EMI technique is the use of Lead Zirconate Titanate (PZT) patches which function as an actuator as well as a sensor. End plate steel beam-column connection is a very crucial member of the steel structure. In this research, a deficient end plate steel beam-column connection subsequently strengthened with carbon fibre reinforced polymer sheets was simulated using a finite element analysis software ANSYS. The health monitoring of this member was performed using modelled PZT transducer in ANSYS itself. It was concluded that the simulated electro-mechanical impedance technique using finite element software was capable of identifying the defects or deficiency as well as strength gained by means of retrofitting
