The preservation of our aging inventory of bridges has become one of the most pressing challenges facing transportation agencies across the country. By some estimates, approximately 30% of existing bridges are either structurally deficient or functionally obsolete. Clearly, there is a pressing need for effective bridge management strategies in order to optimize the utilization of the scarce resources available for maintenance, repair and replacement. With this in mind, the proposed research program will investigate two critical aspects of modern bridge management systems, namely condition assessment and life cycle performance prediction.

保护我们老化的桥梁库存已成为全国交通机构面临的最紧迫的挑战之一。 据估计，大约30%的现有桥梁要么结构缺陷，要么功能过时。显然，迫切需要有效的桥梁管理战略，以优化利用可用于维护、维修和更换的稀缺资源。考虑到这一点，拟议的研究计划将调查现代桥梁管理系统的两个关键方面，即状态评估和生命周期性能预测。
