N2 - The process of structural identification (St-Id) as a means of mitigating uncertainty in the analysis and basic decision-making for a single structure is an established and reliable tool for an engineer or bridge owner. The authors have been utilizing St-Id over the past 20 years for structures varying from highway overpasses to signature long-span bridges. However, the application of St-Id as a tool for management of a large population of assets is a relatively new concept. This paper will address how St-Id can best be utilized within the umbrella of asset management (AM) for a population of similar bridges; a common situation a State DOT may face. The foundation of using St-Id in AM is to estimate vulnerability of a population of structures in order to assess risk and facilitate the determination of appropriate candidates for further investigation from a cost-benefit perspective. Then the selection of fundamental St-Id procedures, including initial investigations, instrumentation, modeling, load testing, dynamic testing and data processing must be chosen based on the specific attributes of the selected structure.
