Abstract

There are many factors that play a role in the overall cost of any bridge. The life cycle cost needs deep knowledge of bridge components to calculate its subcategories costs. The bridge life cycle cost is divided into; agency, user cost, and society costs. The agency cost includes the expected value of the final bridge construction cost, the inspection cost, better value of repainting cost, and replacing asphaltic deck cost. The user cost includes traffic delay cost and vehicle operation cost under different traffic conditions, accident cost, and failure cost. The society cost includes aesthetical and environmental impact. All costs are estimated during the same analysis period.

This thesis focuses on using a mathematical life cycle cost model for bridges that emphasizes on the agency, user, and society costs of a bridge over its useful life. MATLAB program is used to build a program that is used to calculate the life cycle cost of any bridges based on its characteristics.

The mathematical life cycle model for bridges is calculated in six different case studies in Michigan state. “Pontis 4”, which is a database of bridges, and Michigan department of transportation MDOT are both used to get the bridges characteristics for each case study.
