  HSLA-V Steel Non-Standard Fixed Bridge

Project Background

The U.S. Army maintains bridge designs for rapid reconstruction during deployed operations. However, heavy military loads and the materials required to support these loads often limit these bridges to short spans. The U.S. Army has need of bridges which can span long gaps and are readily deployable. HSLA-V steels are now used in girders and plates for highway bridges in the private sector, as they offer stronger, yet lighter weight structures. As an economical alternative to standard low C-Mn steels, HSLA-V steels are also easier to weld, exhibit a higher toughness, and are more resistant to the effects of corrosion.

Project Objective

The Department of Civil and Environmental Engineering at the University of South Carolina (USC) and the Engineering Research and Development Center (ERDC) of the U.S. Army Corps of Engineers have agreed to jointly investigate the benefits of HSLA-V steel and the utilization of existing private sector bridge technology in the redesign of current Army non-standard fixed bridges for rapid construction and minimized weight.
