Experimental Study On Remaining Tensile Strength Of Wide Steel Specimens With Different Corrosion Conditions

In recent years, the maintenance techniques in steel bridge management system have been becoming more and more serious problem in Japan. This paper presents more accurate remaining strength estimation method for tensile corroded members. For this purpose, the tensile test and steel surface measurement of severe corroded specimens were carried out in this study. Most important features of this tensile test are that all 26 specimens have wide width (70-180 mm: actual member size) and totally different corroded conditions. The 3-dimensional scanning system had been applied to steel surface measurement in order to investigate the relationship between the remaining strength and statistical features of surface irregularities. From the experimental results, main conclusions of this study are follows: (1) Influence of stress concentration due to surface irregularities appear clearly around yield load stage. (2) Aminimum thickness (t_) and its position are very important to estimate the remaining tensile strength. (3) A simple estimation method, which used a new statistical parameter t_/t_0 (t_0: original thickness), was proposed for the remaining tensile strength of corroded plate members.conference pape
