Abstract:The safety and condition of the national transportation infrastructure has been at the forefront of national debates in recent times due to catastrophic bridge failures occurred in the United States, but the issue has been a longstanding challenge for transportation agencies for many years as resources continue to diminish. The ASCE’s 2013 report card for America’s Infrastructure assigned in-service bridges a score of C+, which reflects the extent of deteriorating conditions and deficiency of the national aging infrastructure network. Currently, transportation officials rely heavily on experienced-based practices to make decisions regarding maintenance and preservation of the bridge inventory. Several inspection methods and monitoring techniques have been developed and used by the bridge owners to monitor the in-service behavior and detect deteriorating conditions. Despite successful implementation of these methods, the lack of a rational understanding of the system-level behavior of in-service structures, especially in the presence of damage and deterioration, makes resolving this problem even more complicated. This constraint, coupled with limited resources and the vast network of existing structures in service, highlights the need to develop systematic strategies to help engineers better understand the system performance and estimate the remaining service life of these structures, while facilitating and supporting maintenance/preservation decision making process.
