To model the displacement-load characteristics of the aged steel-pipe threaded joint, fracture experiments were conducted using specimens with a burial period of 30 to 50 years. The obtained results showed that the maximum tensile load tended to decrease as the burial period became longer and as the internal corrosion became severe. The deterioration of steel pipe threaded joints was represented by a model in which the yield load and maximum load decrease as the pipe thickness decreases in proportion to the 0.5th power of the burial period t due to corrosion. The seismic response of the system is investigated by modeling the pipe with beam elements and the deteriorated joints as well as the pipe-soil interaction with spring elements. It is shown that joints with a burial period of more than 20 years are plasticized with a ground strain of 0.3%, and joints with a burial period of 50 years are destroyed with a ground strain of 0.5%. As a result, the effect of joint deterioration on the seismic performance of the steel pipe conduits was quantitatively clarified.","PeriodicalId":16804,"journal":{"name":"Journal of Pipeline Systems Engineering and Practice","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135857974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Piratla, Ilya Safro","doi":"10.1061/jpsea2.pseng-1358","DOIUrl":"https://doi.org/10.1061/jpsea2.pseng-1358","url":null,"abstract":": Rare or limited access to real-world data has widely been a stumbling block for the development and employment of design optimization and simulation models in water distribution systems (WDS). Primary reasons for such accessibility issues could include data unavailability and high security protocols. Synthetic data can play a major role as a reliable alternative to mimic and replicate real-world WDS for modeling purposes. This study puts forth a comprehensive approach to generate synthetic WDS infrastructural data by (1) employing graph-theory concepts to generate multitudinous WDS skeleton layouts through retaining the critical topological features of a given real WDS; and (2) assigning component sizes and operational features such as nodal demands, pump curves, pipe sizes, and tank elevations to the generated WDS skeleton layouts through a multiobjective genetic algorithm (GA) – based design optimization scheme. Thousands of such generated-optimized networks are statistically analyzed in terms of the fundamental WDS characteristics both collectively and granularly. An outstanding novelty in this study includes an automatedly integrated algorithmic function that attempts to (1) simultaneously optimize the generated network in a biobjective scheme, (2) rectify pipe intersections that violate pipeline embedding standards, and (3) correct the unusual triangular loops in the generator by honoring the conventional square-shaped loop connectivity in a WDS. The proposed modeling approach was demonstrated in this study using the popular Anytown water distribution benchmark system. Generation and optimization of such representative synthetic networks pave the way for extensive access to representative case-study models for academic and industrial purposes while the security of the real-world infrastructure data is not compromised.
