Steel pipe piles constructed in marine environment have been damaged bittely by corrosion after long term. Damage is concentrated in steel pipe pile at sprash zone. Some steel pipe piles are lack of strength which is necessary for external forces. Some repair methods are proposed for corroded steel pipe pile. Repair method by reinforced concrete coverage is one of effective methods but design method of this repair work is not enough arranged. Bending loading test and push out loading test are carried out to know mechanical properties due to bending moment and axial force and to confirm applicability of a conventional design method. Through loading tests, ultimate strength, crack development, deformation and so on of test specimen are investigated.
