N2 - In this paper, we propose a framework to monitor multiple distress condition measurements of structural facilities simultaneously. Multivariate statistical process control methods were employed to: 1) reduce the dimension of data; 2) capture the interrelations among distresses and; 3) rigorously control the false alarm rate.We implemented the methods to monitor the long-term fatigue process of the Hurley Bridge on the border ofWisconsin and Michigan. Real-time measurements were collected on the strains and displacements at critical locations of the bridge while weather and traffic conditions were sampled over the same period to account for exogenous factors. Empirical studies signaled suspicious events with predetermined confidence and identified plausible sources. The results demonstrate that the proposed framework is effective in field practices.
