中文摘要	Existing steel railway bridges are often required to carry an increasing volume of traffic, usually consisting of trucks heavier than those considered in the original design. Therefore, the service safety of such bridges is a topic of considerable importance. A double-angle probabilistic fracture failure model for riveted bridge members was developed based on an analysis of the fatigue failure mechanism of riveted steel bridges. The model is the basis for a systems fatigue reliability model for riveted steel bridges using the Monte-Carlo method in a large systems fatigue reliability analysis program to predict the system fatigue failure probability of existing riveted bridges. The systems fatigue reliability model was used to predict the systems fatigue reliability of the Ganjiang Railway Bridge of the Jingjiu Railway in China. The probabilistic remaining fatigue life assessment was used to set the inspection intervals for the upriver railway deck systems for assuring normal service function at 1.7 years, with downriver inspection intervals of 0.6 year. The inspection intervals for assuring the load-carrying capacity of the main truss systems is 3.7 years.
