Abstract

This paper presents a risk-based seismic restoration cost curve generation framework for curved steel bridges. The framework uses response surface metamodels (RSMs) in conjunction with Monte Carlo Simulation (MCS) for the generation of seismic restoration cost curves on such bridges. The framework is applied to a sample of curved steel bridges located in low seismic areas of the United States. The combined RSM-MCS models are employed to create seismic fragility curves for the selected bridges and calculate their damage ratios. Risked-based damage factor models coupled with secondary MCS enabling the treatment of variability in damage ratios and bridge features are simulated through the RSM-based fragility curves. Resulting restoration cost curves are generated using average restoration cost data in the United States. The proposed framework is capable of efficiently estimating restoration cost for such bridges under seismic hazards and to potentially aiding in making rational decisions concerning their appropriate retrofit and rehabilitation.
