Concrete columns are critical in supporting the weight of an entire structural frame and also play a key role in force transferring among structural members.
Therefore, integrity of the columns, especially their axial load bearing capacity, directly affects the stability and safety of the entire structure.
In this study, a wearable smart hoop is designed to monitor the axial load of the concrete columns.
The smart hoop measures the shift in impedance frequency of its integrated piezoelectric transducer and correlates the frequency to the structural state of the column.
In order to validate the feasibility of the smart hoop, an experiment on two concrete columns with different dimensions is carried out.
The smart hoop is installed on each column.
Then, an increasing axial load was applied onto the specimen, and the admittance of the PZT patch is acquired under different load levels by using an impedance analyzer.
Finally, frequencies corresponding to the peak and trough in the susceptance of the admittance signal are collected as the monitoring index to estimate the axial load variation on the specimen.
The experimental results demonstrated a downward shift in frequency corresponding to an increase of axial load.
The results validate the feasibility of the wearable smart hoop in monitoring axial load for concrete columns and show potential for retrofit on existing columns.
