Bridges are the substantial part of the transportation infrastructure. Most recent report shows that of the 605,086 bridges in the United States, 67,526 (11%) are deemed structurally deficient, and 76,363 (13%) are declared functionally obsolete (FHWA, 2011). Deck is the shelter of a bridge that is subjected to severe loads due to exposure and traffic. Importance of detecting deck deterioration is further highlighted with the introduction of accelerated bridge construction (ABC) where prefabricated components are brought to the site, assembled, and connected using field cast joints. However, durability performance of field cast connections is not encouraging. Hence, continuous monitoring of structural integrity of bridges built using prefabricated components is vital to detect onset of deterioration. The thesis focuses on developing a tool based on statistical model(s) to present the structural health monitoring data in a meaningful and easily understood format and combining the statistical model(s) and detailed numerical model for damage detection is examined to simulate possible joint failure.
