AN EXPERT SYSTEM FOR EVALUATING STRUCTURAL DURABILITY OF RC BRIDGE DECKS

Assessing the Performance of Corroding RC Bridge Decks: A Critical Review of Corrosion Propagation Models

Corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (RC) structures deterioration in chloride-contaminated environments. As a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. The corrosion propagation phase is a ...

An Expert System for Evaluating

Scour is the erosion of bed and bank material by flowing water; scour poses a threat to bridge security by undermining piers and abutments over time. In fact, “the most common cause of bridge failures is floods with the scouring of bridge foundations being the most common cause of flood damage” (Richardson et al., 1993). While regular inspections and maintenance reduce the risk of a scourrelate...

Durability Monitoring for Improved Service Life Predictions of Concrete Bridge Decks in Corrosive Environments

The development of an effective strategy for the inspection and monitoring of the nation’s critical bridges has become necessary due to aging, increased traffic loads, changing environmental conditions, and advanced deterioration. This article presents the development of a probabilistic mechanistic modeling approach supported by durability monitoring to obtain improved predictions of service li...

Correlation-based Model for Evaluating Ground Penetrating Radar (gpr) Data of Concrete Bridge Decks

The Ground Penetrating Radar (GPR) has been studied for a long time as a non-destructive evaluation (NDE) technology for inspection of concrete structures. Currently, the most widely used technique for interpreting GPR data of concrete bridge decks is the one that based on the amplitudes measured at various interfaces such as asphalt-concrete, top rebar, or slab bottom. The assumption behind th...
