ABSTRACT
This paper experimentally investigates the tensile and compressive behaviors of corroded steel stiffened plates and evaluates the effects of pitting- and grooving-corrosion damages on the residual strengths of corroded stiffened plates. Two series of tests were conducted for this study. One is the tensile tests on specimens having natural corrosions and artificially machined corrosions. The other one is the compression tests on damaged stiffened plates having artificially machined corrosions. Naturally corroded tensile specimens were obtained from an aged ship. The profiles of the naturally corroded tensile specimens were measured using a three-dimensional scanner and a dial thickness gauge. Tensile tests were conducted on nine naturally corroded and fifteen artificially machined specimens. Compression tests were also performed on seven stiffened plates having artificially machined corrosion damages. Pitting- and grooving-corrosions were considered in the compression tests.
