Life-Time Reliability Profiles for Fatigue and Corrosion

Corrosion and fatigue are important considerations that affect the structural performance of bridges and this applies to structural steel, reinforced concrete, and prestressed concrete. The optimum management of bridges requires the prediction of the remaining life for partially deteriorated structures. Therefore, this paper deals with the development of reliability-based models for time-varying changes in structural performance due to corrosion and fatigue. Fatigue limit state is one of the important considerations in the design of bridges. Accumulated load cycles can cause cracking or even failure. Reliability analysis is performed for the fatigue limit state function of flexure. Prediction of the remaining fatigue life for steel and concrete beams is illustrated by using examples of existing bridge girders. Corrosion causes a loss of the section and reduction of the load carrying capacity and the rate of corrosion is a random variable. Three levels of corrosion are considered in the paper and the changes in reliability are evaluated as a function of time, which covers the life-time of the bridge.
