RELIABILITY-BASED EVALUATION OF REHABILITATION RATES OF BRIDGE GROUPS

Open publisher page 6 citations

Abstract

Recent studies indicate that similar bridges designed and constructed to the same requirements end up with different reliability levels even when they are just opened to traffic. Several studies also indicate that the deterioration rates of these bridges are different. As a result, the likelihood of occurrence of limit state violation at any stage during the intended service life of a group of similar bridges has to be based on whole-life performance reliability studies. This paper presents results of a lifetime reliability-based methodology for the prediction of rehabilitation rates of bridge groups under different maintenance regimes. This prediction provides a rational basis for selecting optimum maintenance strategies for different bridge types. (A) For the covering abstract see ITRD E121600.
