A systems-based approach for evaluating the utility of structural health monitoring methods in bridge engineering applications is presented. The vehicle for this evaluation is a systems management model developed within a computationally tractable decision support framework called a Partially Observable Markov Decision Process (POMDP). A major component of this work was the investigation of the complex relationship that exists between 'damage' as inferred from global measurements (e.g., natural frequency and mode shape) and the actual resistance or capacity of a structural system. The concept of a relationship matrix is presented as a means of representing this relationship mathematically. In addition, a simplified example is offered to illustrate how relationship matrices can be assembled via simulation. Finally, the potential implications of this research are discussed.
