Reliability-based control criteria for measured monitoring data

초록

Most operating bridges collect data from measurement systems with various types of sensors and evaluate their health conditions. Since the statistical distribution of measured information may have different characteristics depending on the types of sensors or characteristic events developed during the measurements, however, it is not easy to keep managing the measured data in a consistent manner. The paper introduces a systematic way of resetting the safety control criteria for the measured monitoring data based on the statistical aspects of the measured data. The proposed statistical approach has been examined with actually measured time-history data from a bridge structure.
