Novel Cost-Based Performance Index for Condition Assessment of Bridges: Case Study for an Ohio Bridge

Bridges are key components in transportation systems in Ohio and are essential in supporting various economic activities at local and state levels. These structures deteriorate differently due to differences in exposure to various environmental stressors and service loads, and having diverse ages, configurations, and structural features. Moreover, the amount of budget to maintain, repair and replace bridges in Ohio which has the second largest number of bridges in the United States is limited. These factors, among others, pose a challenge for evaluating the performance of these structures and managing their safety and serviceability. This study presents a practical and efficient measure called bridge condition index (BCI) for reliable condition assessment of Ohio bridges through effective utilization of Ohio Department of Transportation’s bridge databases. Ohio BCI (OBCI) is intended to evaluate bridges at element-, component-, bridge-, and network-levels and to reflect the impact of defects as well as condition enhancement of individual elements on the condition-state of the system. In order to compare direct and indirect consequences of various conditions of bridges on users and agencies, a unified metric based on cost is proposed for the OBCI formulation. This index is demonstrated for a real bridge in Ohio. To examine the efficiency of the OBCI, the results are compared to Bridge Health Index which is a common bridge performance metric. Furthermore, the ability of OBCI to account for effects of bridge serviceability features such as average daily traffic is shown. The proposed metric can assist in proper maintenance of transportation systems and enhancement of their serviceability and safety.
