During the last 5-10 years there has been considerable activity in research and development of fibre composites in the Australian civil engineering market. Areas of activity have included; bridge systems, replacement of large-section hardwood girders, waterfront structures and railway sleepers. The work has involved not only the initial concept development, but also the construction and deployment of full-scale prototypes. Through close involvement of major asset owners, including state road and rail authorities and city councils, these technologies have evolved from initial technology demonstrators to become viable commercial alternatives to traditional structural solutions. This paper presents a review of these developments and examines the process involved in taking these new systems from a novelty to a viable and credible alternative for local asset owners.
<p>Gradual deterioration of concrete structures due to alkali-silica reaction (ASR) and other mechanisms is a worldwide issue which is especially concerning for bridges. Currently, the point at which such deterioration begins to significantly impact structural capacity is not clearly defined. In this study, long-term continuous strain monitoring instrumentation was installed on a deteriorating Queensland bridge in order to monitor structural performance and support ongoing management. Short-term conventional instrumentation was also installed, and a grillage model was developed in order to facilitate benchmarking and validation of the long-term system. This paper describes the rationale, selection of instrumentation and presents initial results.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
