Development of a Field-Portable Small-Size Impedance Analyzer for Structural Health Monitoring using the Electromechanical Impedance Technique
Electromechanical (E/M) impedance method is emerging as an effective and powerful technique for structural health monitoring. The E/M impedance method utilizes as its main apparatus an impedance analyzer that reads the in-situ E/M impedance of piezoelectric wafer active sensors (PWAS) attached to the monitored structure. Laboratory-type impedance analyzers (e.g. HP4194) are bulky, heavy, and ex...
متن کاملSub-Frequency Interval Approach in Electromechanical Impedance Technique for Concrete Structure Health Monitoring
The electromechanical (EM) impedance technique using piezoelectric lead zirconate titanate (PZT) transducers for structural health monitoring (SHM) has attracted considerable attention in various engineering fields. In the conventional EM impedance technique, the EM admittance of a PZT transducer is used as a damage indicator. Statistical analysis methods such as root mean square deviation (RMS...
متن کاملNumerical study of the linear polarization resistance technique applied to reinforced concrete for corrosion assessment
RÉSUMÉ. La technique de résistance de polarisation linéaire (Rp) est utiisée de plus en plus fréquemment pour évaluer la cinétique de corrosion des aciers dans le béton armé. Cependant, la technique souffre d’un manque de fiabilité. Afin de mieux appréhender la physique de la mesure, des simulations numériques ont été réalisées. Plusieurs dispositifs ont été simulés. Ces expériences numériques ...
متن کاملSensitivity of PZT Impedance Sensors for Damage Detection of Concrete Structures
Piezoelectric ceramic Lead Zirconate Titanate (PZT) based electro-mechanicalimpedance (EMI) technique for structural health monitoring (SHM) has been successfullyapplied to various engineering systems. However, fundamental research work on thesensitivity of the PZT impedance sensors for damage detection is still in need. In thetraditional EMI method, the PZT electro-mechanical (EM) admittance (...
متن کاملcorrosion detection of reinforced concrete beams with wavelet analysis
corrosion of reinforcing steel and other embedded metals is the main cause of severe deterioration in reinforced concrete structures which subsequently imposes adverse effects on ultimate and serviceability limit state performance of the whole structure. in this paper, a new corrosion detection method for reinforced concrete beams, based on wavelet analysis is presented. to evaluate the capabil...
