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

9506435 Frangopol 该项目的基本目标是开发一种新方法，用于在同时施加适用性、最终和随时间变化的退化要求的情况下，对结构系统进行基于生命周期可靠性的多标准评估和设计。 这项研究将使用最先进的随时间变化的结构可靠性方法。 还将开发将多标准数学规划与时间相关的系统可靠性框架相结合的高效且有效的技术。 该项目的成功完成将能够通过考虑生命周期恶化效应来评估和设计土木工程系统，包括可靠性约束。

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.
