Lifetime Performance Analysis of Existing Reinforced Concrete Bridges. II: Application

This study, the second part of a two part paper, presents the application of a lifetime performance analysis methodology to three reinforced concrete bridges located in an existing bridge network in Colorado. The focus of this paper is on reinforced concrete slabs and girders of the bridges. The limit state equations were previously derived in the companion paper by grouping the random variables, deterministic parameters, and constant coefficients in such a way that the formulas are applicable to reinforced concrete slabs and girders are part of a larger study focusing on lifetime performance analysis of multiple bridge types in a selected bridge network. The bridges are individually described, followed by the presentation of the performance analysis results including both initial reliability indices and lifetime reliability profiles. Once the values associated with random variables, deterministic parameters, and constant coefficients are assigned, component reliability indices for the slab and the girders are calculated for each bridge. Detailed results are presented for an individual bridge, whereas the lifetime reliability profiles are presented for all bridges. For time variant performance analysis, special emphasis is placed on the chloride penetration modeling in reinforced concrete, theoretical basis of which was presented in the companion paper.
