| Abstract: |
The 2017 AS(AS/NZS) 5100Bridge DesignSeries is an evolution of former road authority and (heavy) rail authority standards that can trace their initial roots to 1960s. Originally written in an era when all bridges were owned by public organizations. The 21st century has both public and private ownership of bridges. The scope of transport infrastructure has also expanded and now includes managed motorway gantries, noise barriers and large sign structures This paper has identified an inconsistent approach to scope. It proposes a new wider scope of transport infrastructures to be included in the standard. This consistency in approach will remove inconsistent treatment of non-bridge structures relating to fatigue and load combinations in the current standard. The paper has also identified that high frequency metropolitan trains has resulted in fatigue cycles being grossly underestimated. The paper proposes a name change from bridge to transport infrastructure design to fully capture the scope of the changes. |
