Internationally masonry arch bridges constitute a substantial portion of bridge stocks. An estimated 40% of railway bridges in Europe are of masonry arch construction while in China arch construction of various forms comprises 70% of all bridges. In Ireland an estimated 80% of bridges are of masonry arch construction. Under the National Roads Authority’s (NRA) Eirspan Bridge Management Programme, the 877 masonry arch bridges on the national road network are being assessed. However there are a number of different assessment methods available with a corresponding number of different results for the load capacity of these structures. This has cost implications for both the bridge assessment itself and for the costs associated with load restrictions and strengthening measures. To address this issue, research is being carried out under the NRA’s Research Fellowship Programme to develop a hierarchical assessment framework for the assessment of masonry arch bridges. This will aim to recommend different levels of assessment of increasing complexity, specifying limits of applicability for each and providing guidance on their use.
