Life-Cycle Reliability-Based Evaluation and Design of Deteriorating Structural Systems

9506435 Frangopol本项目的基本目标是开发一种新的方法，为生命周期可靠性为基础的多准则评估和设计的结构系统下的可用性，最终的，和随时间变化的退化要求同时施加。 国家的最先进的时间相关的结构可靠性方法将用于这项研究。 将多准则数学规划与时变系统可靠性框架相结合的有效技术也将得到发展。 该项目的成功完成将导致有可能通过考虑生命周期退化效应来评估和设计土木工程系统，包括可靠性限制。

9506435 Frangopol The essential objective of this project is to develop a new method for life-cycle reliability-based multicriteria evaluation and design of structural systems under serviceability, ultimate, and time-dependent deterioration requirements imposed simultaneously. State-of-the-art time-dependent structural reliability methods will be used in this research. Efficient and effective techniques of combining multicriteria mathematical programming with time- dependent system reliability framework will also be developed. Successful completion of this project will result in the possibility to evaluate and design civil engineering systems, including reliability constraints, by considering life-cycle deterioration effects.
