Abstract

Background:

In this study, piezoelectric sensors were embedded into concrete structures to monitor dynamic response. The embedded piezoelectric sensors had sensitive frequency and linear response.

Objective:

In the experiment, two loading conditions were applied to the concrete cantilever beam and concrete frame. The dynamic properties could be monitored using the embedded sensors and the damage could also be identified.

Keywords: Piezoelectric ceramics, Concrete structure, Dynamic strain response, Sensors, Sensitive frequency, Experiment.
