Laboratory Testing of Innovative Steel Bridge Designs

Ongoing research at Colorado State University (CSU) has considered innovative approaches to design of steel bridges for the Colorado Department of Transportation. An initial study considered the application of compact rolled steel sections to simple made continuous design. A follow-up study is considering steel plate girders along with innovations such as (1) external post tensioning using either steel or FRP rods; (2) use of hybrid steel girders to enable the use of high performance steel in key regions of the girders; (3) use of double composite steel-concrete bridges (see figure below); and (4) application of a FRP cover plate to the bottom flange using epoxy to optimize the cross section. The study currently underway is purely analytical. In order to put these innovative bridge design and construction techniques to use, the analytical models need to be verified by laboratory experiments.
