Abstract: Structural Health monitoring plays a vital role in all generations for the safety of life and property. The method of Electromechanical Impedance (EMI) method and sensors are used in damage detection of civil and mechanical structures. The structure deteriorates due to ageing and environmental factors. This study represents the detection of damage in concrete structure using piezo electric transducer and EMI method. The piezo sensor is bonded to the concrete structure using epoxy resin and damage is created by using flexural testing machine. The force is applied using flexural testing machine at different KiloNewton. The output from the impedance chip is noted at undamaged state and at all levels of applied force. The impedance, admittance, conductance and susceptance curves are drawn with different levels of frequency. Root mean square deviation is also calculated for the detection of damage. The results conclude that Impedance chip is highly reliable and accurate in damage detection of concrete structure.
