A large number of design, construction and maintenance measures may be selected by bridge engineers to help ensure safe and durable service. In the present paper an improved model is developed for time-dependent reliability estimation of RC bridge decks subject to general and localized corrosion. The preliminary model developed is improved by considering weakening of the bond interface between concrete and reinforcement as a result of reinforcement corrosion and serviceability limit states in the time-dependent reliability analysis. A probabilistic model is developed that relates loss of reinforcement area to a non-linear bond stressstrain relationship.
The probability of S-N curve is one of the basic material fatigue reliability analysis and design. Determination of S-N curve is the basis of the fatigue life of obedience lognormal based on the application of statistical methods to fit the experimental data obtained fatigue. This paper studies the construction of reinforced Fatigue S-N Curves overloading effect on the structural performance of the bridge. In this paper, the fatigue reliability theory as a useful supplement, has some theoretical significance and value of work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
