Application of high performance steel in highway bridges
High performance steels made using advanced compositions and/or processing practices have improved mechanical and other properties. Properties such as yield strength, weldability, fracture toughness, ductility, and corrosion resistance are of importance for highway bridges. This paper discusses the use of high performance steels in highway bridges, and the associated benefits and problems to be overcome. The paper focuses on the use of high performance steel in welded steel I-girder highway bridges and shows the potential decreases in steel girder weight from using high performance steels in bridges designed under current design specifications and practice. High performance steels with a yield strength of 485 MPa or less can be effectively used within current practice. The use of high performance steels with higher yield strengths is less effective because of problems with deflections, stability, and fatigue. However, it is possible to take advantage of these steels in I-girder bridges if certain design specifications can be modified and innovations in design are developed. Several design innovations which can overcome these problems are outlined.
