9802151 Chang This project explores how user impacts can be incorporated into methods for assessing the cost effectiveness of seismic risk management measures for infrastructure systems. It seeks to demonstrate how user costs can be applied within the framework of life cycle costs analysis. Life cycle cost analysis, an approach related to benefit/cost analysis, considers maintenance and other long-term costs associated with an investment project in addition to the initial cost of construction. It has the advantage of allowing the assessment of seismic hazard mitigation in the context of routine infrastructure management practice. This is particularly important in the case of infrastructure systems where some types of seismic upgrading procedures (e.g., pipe replacement) may reduce normal maintenance costs as a collateral benefit. Specific tasks include establishing guidelines for consideration for user costs, developing a user cost methodology within the framework of life cycle costs analysis, and implementating two to three case studies using actual urban infrastructure systems in seismically vulnerable regions of the U.S. ***

9802151 Chang 该项目探讨了如何将用户影响纳入评估基础设施系统地震风险管理措施成本效益的方法中。 它旨在展示如何在生命周期成本分析的框架内应用用户成本。 生命周期成本分析是一种与效益/成本分析相关的方法，除了初始建设成本之外，还考虑与投资项目相关的维护成本和其他长期成本。 它的优点是可以在常规基础设施管理实践的背景下评估地震灾害缓解。 这对于基础设施系统来说尤其重要，因为某些类型的抗震升级程序（例如管道更换）可能会降低正常的维护成本，从而带来附带好处。 具体任务包括制定考虑用户成本的指南、在生命周期成本分析框架内开发用户成本方法，以及使用美国地震脆弱地区的实际城市基础设施系统实施两到三个案例研究***
