Steel Bridge Collaboration Guidelines
The American Association of State Highway & Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) have jointly released two new steel bridge collaboration publications.
The Specification for Structural Duplex Stainless Steel Bridge Plate Materials offers a single unified set of guide specifications developed for duplex stainless steel plate girder bridges. Based on the framework of AASHTO Materials Specification M 270M/M 270 (ASTM A709/A709M), the guide establishes the material requirements for duplex stainless-steel plates used in bridge construction.
The Specification for Design of Structural Duplex Stainless Steel Bridges provides guidance for I-girder bridge superstructures fabricated from duplex stainless steel. While focused on I-girder bridges, the provisions may be adapted for other bridge types by considering the distinct buckling behavior and increased flexibility of duplex stainless-steel members.
Both publications are available free of charge at the AASHTO Store
