N2  - An economic analysis procedure has been developed to assist in the decision-making process for replacing or strengthening a bridge having a deficient load-carrying capacity. Often, decisions are made either to strengthen or replace the structure by considering only the initial costs of each alternative without regard to life-cycle costs. The analysis procedure developed in this study determines an equivalent uniform annual cost for each alternative from which the most cost-effective alternative can be chosen. In addition, this procedure also allows cost comparisons to be made among various applicable strengthening methods. The equivalent uniform annual-cost procedures are based on mathematical models, commonly used in engineering economy studies, that involve cost comparisons between alternatives of different economic lives. A brief discussion of the life-cycle costs used in the mathematical models, and examples using the models developed, are included.
