文摘
- •
Damage assessment of concrete reinforcing bars using bonded piezoelectric patches.
- •
Tests performed in single bars with predefined and artificially induced damages.
- •
Large scale reinforced concrete beams under flexural load with bonded PZTs in bars.
- •
Sensitivity, damage detection ability and influence locus of PZTs is investigated.
- •
PZT admittance curves, RMSD indices and beams’ cracking patterns are presented.
