 note = {Many coastal and offshore steel structures are in need of repair or strengthening due to corrosion problems. The use of steel patch plates welded underwater over corrosion-damaged areas is one of the most common repair procedures for corroded submerged steel pipe and sheet piles. A patch plate thickness, a required weld length, a size of a patch plate, etc. are the design parameters of the repair design. To determine these design parameters efficiently and achieve an effective repair design, strength of a repaired structural member has to be accurately evaluated. This paper summarizes an experimental study of steel pipes repaired with welded patch plates to evaluate the strength recovery resulting from repair. In this study, the thickness of a portion of steel pipes was reduced by half to simulate a reduction of the cross section from corrosion, and steel patch plates were fillet-welded to the pipes with a reduced thickness area. One set of specimens were welded in the open air, and the other welded in the underwater wet environment to understand effects of welding environments on strength of repaired pipes. The repaired pipes were tested in flexure or compression until failure. Based on the experimental results, stiffness and strength recoveries were evaluated, and the effectiveness of patch plates was also examined.},
