Time-dependent reliability analyses are increasingly used to predict structural performance and develop an optimum lifetime maintenance strategy for structural systems, including highway bridges. These analyses require a significant amount of input data and predict structural behavior over several decades. The input data must be updated through inspection. While targeted nondestructive evaluation inspections are preferred, they can be expensive and are not available for all bridges. Biannual visual inspection programs are in place for the nation's highway bridges, and states use bridge management systems (BMSs) to ensure public safety and prioritize the use of scarce maintenance funds. To update the reliability analysis of a highway bridge, the data in the current Pontis BMS must be revised for use of data from visual inspection. Suggestions include a segment-based inspection that gives the analyst the location of defects on the bridge. Also proposed are conservative assumptions, numerical quantification of condition-state descriptions, and linear deterioration of condition states over time. The suggestions were illustrated on a sample highway bridge with defects that can be observed and those that cannot. The strengths and limitations of the proposals were assessed.
