Abstract

Post-earthquake repair costs and repair times are important for evaluating the performance of new bridge design options and existing bridges in preparation for the next major earthquake. Hazard and structural demand models describe the probabilistic structural response during earthquakes. Damage and decision models link the structural response to decisions on repair actions and costs. This paper proposes a step-by-step probabilistic methodology to evaluate repair metrics for different bridge components and the bridge as a system, corresponding to varying degrees of damage. Repair actions, quantities, times, and costs are input into spreadsheet templates, and a numerical tool evaluates the expected value and variance of both repair costs and repair times for a range of earthquake intensities. This methodology uses the concept of performance groups - groups defined to account for bridge components that are repaired together. Data can be customized for repair methods and bridge types particular to different regions. © 2009 ASCE.
