Abstract
In this study, a corrosion accelerating test and loading tests were carried out for specimens of high strength bolted joints to clarify the relationship between corrosion and remaining strength of the corroded joints in the inner or outer surface. In the corrosion accelerating test, corrosion condition of the bolts and the inner surface of the joint, roughness and bolt axial force etc were measured. In the loading tests, slip coefficient, slip strength, yielding strength and maximum strength were obtained.
From the results of the tests, the slip strength and the slip coefficient are increased and the bolt axial force is decreased because red and black rust are generated and increased in the inner surface of the joint. The yielding strength and the maximum strength are little changed in the tests.
