Hybrid Comes Standard: Technique Makes High-Performance Steel Construction more Feasible in Missouri

This article describes a bridge construction project in Missouri demonstrating ways to incorporate high-performance steel (HPS) as a component with conventional materials to take advantage of HPS’s special characteristics without incurring excess costs. The Missouri DOT built the state’s first HPS bridge in 2002 as part of the Federal Highway Administration (FHWA) Innovative Bridge Research and Construction Program. The girders are hybrid with HPS used for the bottom flange in the composite positive-moment region and for both flanges in the noncomposite-negative moment region. The DOT worked with university researchers to instrument, field test, analyze and evaluate the service performance of the new, lighter material. Results of the analysis are given, and they show that the bridge performed well.
