44 Summary The overall objective of this research project was to Establish a framework to evaluate the in-service condition of bridge superstructures. Provide a measure of system performance Characterize the impact of damage on the capacity, redundancy, and safety. The investigation was limited to composite steel girder bridges Illustrate a conceptual schematic of a computational modeling strategy Study the influence of corrosion in steel girders and delamination in concrete decks Corrosion has major impact on the behavior of the system, with the level of effectiveness highly depends on the damage extent level. Delamination has minor impact on non-linear behavior of the system, while it may reduce the functionality governed by premature failure modes. The proposed framework could be beneficial to the preservation community as a mechanism to make decisions based on in-service condition. It can provide a critical linkage between the design and preservation communities by correlating the element-level and system-level responses. 37
