This paper presents a study on performance of piled jetty steel pipe repaired by steel patch plate. In this study, repaired steel pipes of piled jetty are modeled. The whole model of piled jetty is analyzed by finite element method. In FE model, shell elements, pipe elements, beam elements and spring elements are used. The bi-linear force-displacement relationship is used for spring elements to represent horizontal resistance of soil. Variation of corrosion thickness is modeled by using actual data of corroded steel pipe. From numerical results, the buckling behavior of repaired steel pipe of piled jetty is clarified. It is shown that a required thickness of patch plate is larger than thickness reduction to achieve the same level of ductility performance in the repaired pipe as intact pipe.
