Abstract

In this study probabilistic seismic loss models for reinforced concrete bridges are improved with separate models for connecting damage to repair quantities and repair quantities to money and time costs. This approach allows explicit consideration of repair design and variability of cost and time estimating that are not captured using a direct relationship between damage and loss. The proposed repair and cost models require schematic designs of bridge repairs and cost estimations to determine the model parameters, which were completed for three scenarios of damage on a single bridge. These models were used to analyze the probabilistic losses on different bridge types, specifically repair costs and repair effort. These analyses can be utilized for direct and indirect seismic loss assessments for transportation networks. All data in the proposed models were parameterized in terms of bridge properties, allowing extrapolation to bridges within the same class. The procedure is also portable for different bridge classes and state practices. [DOI: 10.1193/1.3651362]
