9912525FrangopolThe main objective of this research is to develop a framework for balancing bridge system reliability and expected life-cycle cost of bridge maintenance programs. This framework will provide the methodology for optimum bridge maintenance based on system reliability in a cycle perspective. The challenge in using the proposed framework is quantifying the uncertainties in the input variables. The information from bridge performance data, maintenance data, cost data, and engineering judgement can be combined, used, systematically updated and related directly to the optimum solution. The proposed approach will permit the process of optimum lifetime planning of bridge maintenance programs to evolve rationally and to be cost-effective.

本研究的主要目的是建立一个平衡桥梁系统可靠性和桥梁维修计划的预期寿命周期成本的框架。该框架将提供基于周期角度的系统可靠性的最佳桥梁维护方法。使用所提出的框架的挑战是量化输入变量中的不确定性。来自桥梁性能数据、维护数据、成本数据和工程判断的信息可以组合、使用、系统更新并直接与最佳解决方案相关。所提出的方法将使桥梁维护方案的最佳寿命规划过程合理发展，并具有成本效益。
