Title

Carbon Footprint Of Post-Earthquake Bridge Repair

Abstract

Previous performance-based earthquake engineering investigations on highway bridges focused on repair cost and repair time metrics. These are primarily related to economic life cycle-cost analysis decision-making strategies for evaluating the vulnerability of bridge infrastructure. However, equally important considerations for decision making are those associated with the complete life-cycle assessment of the same infrastructure. Quantifying the sustainability of bridge designs using carbon footprint as the performance metric is investigated in this paper. A set of multi-span reinforced concrete highway overpass bridges in California is used to illustrate the probabilistic carbon accounting methodology. The bridges were selected because repair cost and time data are already available, allowing comparison of the cost-based performance metrics with the derived sustainability metrics. The performance groups and material quantities that drive the major contributions to carbon footprint as compared to economic costs are presented.
