Development of Optimized Decked Bulb-Tee Girders for Alaska

The goal of this project is to develop an optimization approach for pre-tensioned decked bulb-tee girders for systematically identifying new optimized cross-section shapes, while considering the deck and the numbers of spans and girders, that address the many quantitative and subjective constraints. This project includes lab testing, a literature review, cost-optimization, data analysis, performance analysis, recommendations for DOT, and a workshop with a final report.
