Abstract

Masonry arch bridges, most of which have far exceeded modern design lives, have demonstrated themselves to be sustainable structures with low life-cycle costs. However increased traffic loading and material deterioration over time necessitate reassessment of these structures. There are numerous different analytical methods available for the assessment of masonry arch bridges, with an equally diverse range of results. Generally, the expectation would be that for increasing levels of assessment complexity an increase in load capacity would be achieved. However, as the results presented in this paper demonstrate this is not always the case. This paper describes a programme of research being carried out under the National Roads Authority’s Research Fellowship Programme to develop a hierarchical assessment framework for masonry arch bridges in order to address this issue. It is envisaged that the assessment framework will include both existing methods and methods developed within this project and will aim to recommend different levels of assessment, specifying limits of applicability for each and providing guidance on their use.
