Investigation of Dual Grade / Hybrid Steel Plate Girders Utilizing Stainless Steel

The objective of this research is to examine the feasibility of connecting bridge-construction approved ASTM stainless steel (currently only Grade 50CR is approved) to conventional steel (Grade 36, 50, 50W, etc.) through welding or bolting and to develop guidelines to assist designers and fabricators when connecting stainless steel plates to conventional steel plates in the superstructure of highway bridges. The guidelines would be considered a supplemental document to the AASHTO LRFD Bridge Design Specifications and the AASHTO LRFD Bridge Construction Specifications.
