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.

在研究系统可靠性评估方法的同时， 广泛地说，实际包括系统的可靠性， 设计水平受到的关注相对较少。 在 设计一个结构，最终考虑的是系统的可靠性 而不是单个组件的可靠性。 然而，在这方面， 现有的基于可靠性的设计方法是基于组件的。 本项目的目标是开发一个模型系统- 基于可靠性的LRFD方法 由于提案人有广泛的 经验与传输结构，该模型LRFD方法 将适用于输电结构的设计。 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，设计师和公用事业公司可以 用于将系统可靠性纳入设计 传输结构。 第二阶段将使用计算机 从第一阶段开始，扩大调查人员的组成部分- 用于传输结构的基于RBD的方法， 可靠性能力。 该项目寻求NSF的50%共同赞助。 美国 以电力研究所为代表的电力行业 研究所，已承诺获得其他50%的资金 该项目所需的。
