Integration of System Reliability in the Structural Design Process System Reliability-Based Design of Transmission Structures

虽然评估系统可靠性的方法正在被广泛研究，但在设计层面实际纳入系统可靠性却受到相对较少的关注。在设计结构时，最终考虑的是系统的可靠性，而不是单个部件的可靠性。然而，现有的基于可靠性的设计方法是基于组件的。本课题的目标是开发一种基于模型系统可靠性的lrfd方法。由于作者具有丰富的传动结构设计经验，因此该模型LRFD方法将适用于电力传动结构的设计。该项目将分两个阶段进行。第一阶段将开发一个计算机程序，设计人员和公用事业公司可以使用该程序将系统可靠性纳入传输结构的设计中。第二阶段将使用第一阶段的计算机程序扩展研究人员基于组件的RBD方法，用于传输结构，以包括系统可靠性能力。该项目正在寻求国家科学基金会50%的共同赞助。以电力研究所（Electric power Research Institute）为代表的美国电力行业已承诺获得该项目所需资金的另外50%。

While methods to estimate system reliability are being studied extensively, the practical inclusion of system reliability at the design level has received comparatively little attention. In designing a structure, the ultimate concern is system reliability rather than individual component reliabilities. However, existing Reliability-Based Design methods are component-based. The objective of this project is to develop a model system- reliability-based-LRFD method. Since the proposers have a wide experience with transmission structures, this model LRFD method will apply to the design of electric transmission structures. The project will be conducted in two phases. The first phase will develop a computer program that designers and utilities can use to incorporate system reliability in the design of transmission structures. The second phase will use the computer program from phase one to extend the investigators component- based RBD method for transmission structures to include system reliability capability. This project is seeking 50% co-sponsorship from NSF. The U.S. power industry, represented by the Electric Power Research Institute, has committed to obtain the other 50% of the funds required for this project.
