Project Objective

To produce complete design and direct cost comparisons between conventional 50 ksi steel and HPS 70 ksi steel girder bridges.

Project Abstract

With commercial production of High Performance Steel (HPS) states are faced with the questions of using conventional 50-ksi or HPS 70-ksi steel for girder bridges. Research and application examples have demonstrated the quality of material, weldability, fabrication, and erection of HPS, yet states need information on the economics of HPS over conventional steel. This work will produce complete design and direct cost comparisons between conventional 50 ksi steel and HPS 70 ksi steel for a composite two-span (153 ft - 153 ft), four-lane steel girder bridge. Several HPS alternatives will be considered for various girders line and hybrid scenarios.

Task Description

Develop alternative HPS 70 ksi designs and compare to conventional 50 ksi
steel design.

Anticipated Benefits

The results will be published to states as examples of the benefits of HPS bridges.
