This paper presents a study on seismic behavior of steel piled jetty repaired by steel patch plates, and shows a study concerned with a required thickness of steel patch plate. In this study, the whole FE model is used to study the seismic behavior of a piled jetty. Furthermore, the cantilever FE model is examined to propose a required thickness of steel patch plate. From the time history response analysis, it is shown that seismic behavior of the steel piled jetty repaired by steel patch plates becomes almost the same as behavior of the intact piled jetty. Based on pushover analyses of a number of cantilever FE models, an empirical formula to determine the required thickness of patch plate is proposed for the repair design of corroded steel pile.
