| 摘要： | Cost-benefit assessment of bridge maintenance strategies is possible if related expenditures can be correctly evaluated over an appropriate life cycle and if they produce a known effect on structural performance. A method for such assessment was proposed by the authors in earlier publications and was based on data from the 762 bridges under New York City management. A program was developed for investigating alternative strategies to see not only which gives the lowest life-cycle cost, but also how the various cost components vary over the life of a bridge. The allocation of limited resources to bridge maintenance in optimal fashion was explored using the program, which provided numerical results and formal optimization techniques. |
