In this study, compressive tests were carried out on seamless circular tubular short columns with corrosion-damaged end, and investigated change in compressive strength of columns with local corrosion at the end. Local corrosion was artificially introduced by milling machine, and differed in corrosion depth (0, 1.5, 3, 4.5 mm), corrosion height (0, 20, 60, 120 mm), and corrosion circumference (0, 90, 180, 360˚ ). As a result, the compressive loads were linearly decreased with increasing of corrosion degrees, and a quantitative evaluation for residual compressive strength of seamless circular tubular short column with corrosion-damaged end was suggested by using corroded volume loss ratio.
