Fatigue: it will change our culture
The Austroads SM1600 loading was developed to ensure that bridges were constructed with a 100 year design life in an environment where heavy vehicle masses and dimensions continue to increase for the greater economic benefit of the nation. In the initial development of this loading, the strength and serviceability limit states were considered but not the fatigue limit state. This paper presents the results of an Austroads research project which was designed to develop a new fatigue load model that was consistent with the SM1600 design loading. The findings challenge the current design process and the selection of materials. It raises issues about consistency and how to implement what would be a step change in design culture. Consequently the findings have been debated intensely. This paper documents and encourages the debate with the goal of appropriate fatigue design of bridges that is consistent with the 100 year design life of bridge in an environment of increasing loads.
