The Monitoring Method for Crack Damage of Concrete Structures Based on Piezoceramics Transducers

Abstract:

A method for monitoring the crack damage of concrete structure based on piezoceramics transducers was introduced in the paper. The PZT patches were packaged as smart aggregates which buried into concrete structures in pair. One is as actuator to transmit monitoring signals, and the other is as sensor to receive the monitoring signals. Sine sweep frequency wave was used as monitoring signal type, and its energy value was used as damage identification parameter. At last, a test was conducted to prove the effectiveness of monitoring method. The crack damage of a reinforced concrete beam under the load was monitored during the whole test process. The develop trend of damage identification parameter could reflect the develop trend of damage. The method proposed in the paper is feasible for crack damage monitoring of concrete structure.
