Monitoring Loading Effects of Construction Steel Structure Using Piezo Transducer for Electromechanical Impedance Techniques
In recent constructional practice, piezo sensor-based structural health monitoring (SHM) is one of the most extensively employed and reliable non-destructive evaluation technique in the mechanical, civil, and aerospace industries. With aid of proper installation, optimal location, and reusability, the piezoelectric sensors can be used for evaluation of the performance of a structure and damage identification. This paper addresses, the employability of the multiple piezo configuration approach for electromechanical impedance techniques (EMI) technique for better monitoring the construction steel for different force action and loading effects. The novelty of this study is mainly focused for reusable and non-bonded configuration to rib and curve surface of construction steel, i.e., steel bar. The different positions of the piezo sensor, i.e., surface bonded, metal wire-based and clamp-based arrangements, were chosen to monitor steel bar-imposed axial loads and it’s effect via piezo coupled admittance signatures are recorded. Statistical damage index (RMSD) is evaluated for better quantification for all three proposed sensor configurations. The overall results demonstrate the efficiency of non-bonded and reusable approach for identifying and localizing loading effects on the host structure.
