Study on the Application of Postembedded Piezoceramic Sensors for the Force Detection on RC Columns under Dynamic Loadings
Publication: Earth and Space 2021
ABSTRACT
To quantify damage to a reinforced concrete (RC) column members after an earthquake, the maximum applied force generated by the earthquake is important information for an engineer. Therefore, in this study, the piezoceramic transducers are used to detect the applied force for an RC column member under dynamic loadings. To investigate the use of postembedded piezoceramic sensors in detecting the force that is applied to RC columns, eight full-size RC column specimens with various failure modes are tested under dynamic loadings that are induced by specified earthquakes. Postembedded piezoceramic sensors are installed at a range of depths (7,080 mm) beneath the surface of a column specimen to examine the relationship between the signals that are obtained from them and the force applied by the dynamic actuator. The signals of the postembedded piezoceramic sensors which correlate with the applied force are presented. These results indicate that the postembedded piezoceramic sensors have great potential as a tool for measuring the maximum applied force on an RC column under an earthquake. Restated, for an RC column in an earthquake, signals that are obtained from postembedded piezoceramic sensors can be used to identify the applied force and corresponding damage or residual seismic capacity.
