Abstract
A steel sheet pile in marine environments may have been damaged greatly by corrosion. Reinforced concrete covering is an effective repair technique for such damaged steel sheet piles. The repaired part of the sheet piles can be designed as a composite structure with reinforced concrete and the steel. Its design method and structural details have to be made clear. Loading tests on eight test specimens have been undertaken to investigate their mechanical properties and to verify the design formulae. Through the loading tests, ultimate strength, crack development, and so on depended on the arrangement of shear connectors and concrete cover length.
