This paper will address the measurement and documentation of construction and service effects for a steel stringer bridge in the Cincinnati, Ohio area. It will demonstrate how various monitoring and field testing means can be brought together to evaluate the complete state of force in a bridge over its lifetime, together with the corresponding causative effects or events. Accumulated versus transient stresses and forces are evaluated through a regular regimen of long-term monitoring, diagnostic truckload and modal impact testing, and structural analysis. This research will allow the conceptualization of less understood or unknown phenomena that influence bridge performance, the verification of design assumptions and rating models, and the continued evaluation of emerging technologies for infrastructure monitoring and assessment.
