Abstract: Objective decision making processes are emerging as indispensable tools for bridge managers. Objective relationships between traditional bridge management efforts and management decisions are needed to ensure cost effectiveness and adequate performance. Such tools include conventional decision-making theory, qualitative and quantitative risk management, and life cycle analysis. The advent of high cost demands due to recent natural and man-made disasters have led to an interest in a modern decision-making concept known as “Infrastructure Resiliency”. This paper explores the application of resiliency concepts to bridge structures. This concept has great potential to assist infrastructure owners with multiple asset types to reduce overall risk through appropriate decisions after specific hazards faced by their network.
