This research is focused on the analysis of long-term measurements from distributed sensing of bridges. Previous research has shown that ambient temperatures are strongly correlated with variations in structural response and their influence often exceeds the response to traffic and other loads such as wind. Therefore, characterizing the thermal response is an important first step in interpreting measurements from continuous monitoring. This research hypothesizes that a sensing system, which is comprised of rationally distributed thermocouples as is common in many bridges today, could enable accurate prediction of structural response (strains). Hence, it investigates the following two research questions: (1) could supervised learning techniques such as support vector machines (SVM) be trained to predict structural response from distributed temperature measurements? and (2) could the trained models be employed for anomaly detection? This talk will present preliminary results that support these hypotheses using numerical models of bridges and measurements from a full-scale structure.
