Although pipe pile with interior restraint plate (PPIRP) exhibits significant advantages in bearing performance over open-ended pipe pile (OEPP), comprehensive studies on their bearing characteristics remain limited. This study investigates the compressive and pullout behaviors of OEPP and PPIRP. The research comprises compressive and tensile centrifuge tests of one OEPP and three PPIRPs. Based on recorded load response and soil pressure data, the vertical bearing characteristics of pile foundations are analyzed. The results reveal that the inclusion of an interior restraint plate (IRP) enhances both the compressive bearing capacity and the unit area pullout capacity of OEPP. Furthermore, a soil pressure distribution model at the pile tip is proposed to elucidate the IRP working mechanism. The IRP does not increase the earth pressure near the center of the pile tip, but it enhances the distribution of earth pressure near the pile shaft. A simplified method for evaluating the pile vertical bearing capacity based on the external pullout friction is also proposed. The findings of this study provide valuable insights for optimizing the design and performance of pile foundations.</div></div>","PeriodicalId":19403,"journal":{"name":"Ocean Engineering","volume":"338 ","pages":"Article 121953"},"PeriodicalIF":4.6,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined experimental and numerical analyses have typically provided robust insights into such non-linear mechanical performance. To address challenges in loading, specimen arrangement, data acquisition, and other issues encountered in the full-scale prototype experiments, scaled model experiments are commonly employed. Specifically, distorted models with unequal scale ratios in geometric dimensions and plate thickness are typically used to meet the limitations of loading capacity and the requirements of construction technology. To accurately reveal the ultimate load-carrying capacity and the buckling collapse modes of the prototype, this study proposes a universal scaling design strategy for distorted box girder models used in experiments. The similarity law for achieving the similarity in the ultimate bending moment and collapse modes of the box girder includes the similarity in section properties of the girder and the slenderness of the local stiffened plate. Due to the distortion caused by unequal scaling, the similarity in section properties will be broken. To meet the requirement of the similarity law, this study focuses on the scaling strategy to achieve similarity in the section properties of the deck and bottom simultaneously. A series of comparative scaling strategies were proposed based on the consideration of gradual improvement. Finally, the proposed scaling strategy was verified using numerical results to demonstrate its applicability to any bending case.</div></div>","PeriodicalId":19403,"journal":{"name":"Ocean Engineering","volume":"338 ","pages":"Article 121878"},"PeriodicalIF":4.6,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similar trends were observed in smaller ships, even among vessels with identical designs.
