Damage Monitoring Research of the Concrete Structure Based on the Piezoelectric Impedance
Based on the piezoelectric impedance technology, damages in concrete specimens could be monitored. The structural damages were simulated by pasting piezoelectric ceramic chips and boring several holes on the surface of concrete specimens.

Summary: | Based on the piezoelectric impedance technology, damages in concrete specimens could be monitored. The structural damages were simulated by pasting piezoelectric ceramic chips and boring several holes on the surface of concrete specimens. And then, with the precision impedance analyzer HP4192A, we measured the conductance spectrum curve of the specimens.The specimens were in two different damage situations:one was damaged in one place to varying degrees and the other was damaged in different locations to the same degree. The experiment results show that the damages in the specimens can lead to the drift of the conductance spectrum curve and the greater the damages are, the greater the change will be. |
