A formula for stress‐life curve is proposed to predict the fatigue life of riveted bridges located in corrosive environments. The corrosive environment‐dependent parameters of the S‐N 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 WI‐rivet detail category represent the fatigue strength of riveted members. The proposed S‐N curve formula is compared with full‐scale 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 code‐given 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.

腐蚀环境下铆接细节的S‐N曲线及其在桥梁中的应用

提出了应力-寿命曲线的公式,以预测位于腐蚀性环境中的铆钉桥的疲劳寿命。S‐N曲线的腐蚀环境相关参数是根据空气,淡水和海水中不同类型钢试样的腐蚀疲劳测试结果确定的。欧洲规范详细类别71和英国WI-铆钉详细类别表示铆接构件的疲劳强度。将拟议的S‐N曲线公式与铆接接头,板梁和桁架梁的全尺寸疲劳测试结果进行了比较,并在腐蚀性环境下进行了测试。因此,证实了该公式的有效性。该公式不需要任何材料参数,只要按照代码给出铆接细节的疲劳曲线即可。利用所提出的公式来估算铆接铁路桥梁的疲劳寿命,并将其结果与传统方法进行比较。证实了所提出曲线的适用性和重要性。
