S-N curve for riveted details in corrosive environment and its application to a bridge
A formula for stressâlife curve is proposed to predict the fatigue life of riveted bridges located in corrosive environments. The corrosive environmentâdependent parameters of the SâN curve are determined based on the corrosion fatigue testing results of different types of steel specimens in air, fresh water, and seawater. Eurocode detail category 71 and UK WIârivet detail category represent the fatigue strength of riveted members. The proposed SâN curve formula is compared with fullâscale fatigue test results of riveted joints, plate girders, and truss girders, which were tested in a corrosive environment. Thus, the validity of the formula is confirmed. The formula does not require any material parameter other than the codeâgiven fatigue curve of riveted details. The fatigue life of a riveted railway bridge is estimated by using the proposed formula, and the results are compared with conventional approaches. The applicability and significance of the proposed curve are confirmed.publishedVersio
