Abstract

The use of piezoelectric lead Zirconate Titanate (PZT) transducers is growing in the monitoring of large-scale engineering structures, such skyscrapers and bridges. PZT transducers are implanted in the surface to monitor structures using electro-mechanical impedance or electro-mechanical admittance with PZT and wave transmission with several PZTs. A broader region may be monitored by approach wave propagation with high voltage excitation. Because failure is unexpected and delicate, the condition of reinforced concrete (RC) members at lap splices provided at tension zone is closely observed. The goal of this work is to use PZT to identify damage to the RC beam at steel bar lap splices. PZT were attached on steel bars with varying lap spans to identify damage to reinforced concrete buildings at the steel bar lap zones. Four reinforced concrete beams were used for the tests. The tension bars were spliced in the constant moment zone at lap lengths ranging from 10 to 20 to 30 to 40 times the diameter of a bar (40). At the lap splices, two PZTs were placed separately on each steel rebar. One PZT patch served as an actuator, creating elastic waves that another PZT patch, acting as a sensor, converted into electric impulses and recorded. The signals received were analyzed using wavelet packets and the results were presented.
