A Rapid-Acquisition Electrical Time-Domain Reflectometer for Dynamic Structure Analysis
A rapid-acquisition electrical time-domain reflectometer (TDR) that is capable of acquiring thousands of signatures per second was developed for dynamic structure analysis. The operation of the TDR and its application in the monitoring of dynamic structures are discussed. The TDR was evaluated with a coaxial-cable crack sensor embedded in a full-scale reinforced concrete (RC) column during a 60-s earthquake simulation at the Hyogo Earthquake Engineering Research Center in Japan. The TDR signatures acquired from the sensor during the simulation are analyzed and correlated with the cracks that formed in the RC column.
