High performance steels and their use in structures
Safety, reliability and economy of structures are governed by material, design, fabrication, inspection and maintenance. The most efficient and economical structures are based on optimized trade offs between these parameters. Thus, the use of the best material in combination with deficient design or fabrication or both and the use of the best designs in combination with deficient materials or fabrication of both do not produce safe, reliable or economical structures. This paper describes the effects of composition and thermomechanical processing on the properties of medium carbon 'conventional' steels and on low-carbon 'high-performance' steels. A general discussion of the attributes of high-performance steels and the advantages derived from their use in various structures are presented. The use of high-performance steels for bridges is discussed in more details. This discussion shows that significant benefits may be derived by using high-performance steels in bridges of present design. However, a significant increase in benefits may be achieved by changes in present specifications and by using high-performance steels in new and innovative designs. More important, properties of high-performance steels should be tailored to the needs and requirements of different structural types.
