چکیده
Lifetime of pipelines is very important for safe and sanitary water transmission pipelines and water distribution networks. For this purpose reliability assessment analysis is a good tool and made it easy or feasible to make more better decision for inspections during maintenance and utilization process. In this study, a non-linear state model of corrosion has been used for the structural analysis of corroded water transmission pipelines, stressed by internal pressure and substance corrosion are considered simultaneous base on a limit state function. In order to take the uncertainty associated with the design and environmental variables into account and obtaining failure probability (reliability index), a improved harmony search meta-heuristic optimization algorithm has been selected. Sensitivity analysis of associated parameters is carried out to measure the effectiveness of each ones on the probability of pipe failure. Results obtained for steel pipeline of Karevandar to Kash water transmission project is discussed as a case study.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
