Περίληψη | An integrated monitoring approach for near and far-field damage detection in
concrete structures based on simultaneous use of electromechanical admittance and guided
wave propagation is presented in this work. The proposed sensing system uses arrays of PZT
patches bonded on the surfaces of concrete structures which are serving as multi-mode
sensors/actuators. This innovative technique takes advantage of two PZT basic capabilities:
a) to serve as near-field damage detection sensors using the high-frequency
electromechanical (E/M) admittance monitoring technique and b) to serve as far-field
damage detection sensors using guided wave propagation monitoring technique. In the
guided wave propagation, one PZT patch acts as actuator and launches an elastic wave
through the structure, which then can be measured by another PZT patch which in the same
time serves as admittance sensor. The integration approach of both two methodologies is then
straightforward because the same piezoelectric patch can be used for both methods. This
integration approach is experimentally validated in this work by inspecting the sensing
capabilities of custom-made “multi-mode” sensing system for damage detection of concrete
structures. | en |
