ABSTRACT
In this chapter we review both theoretical and experimental work on the analysis of masonry arch bridges. We start with the very early work and lead on to the assessment method at present in common use in the United Kingdom, the so-called MEXE (Military Engineering Experimental Establishment) method. Its mode of use is described and its limitations are discussed. Because of these limitations, work aimed at either replacing or updating the MEXE method is in progress at the Transport and Road Research Laboratory (TRRL) and elsewhere. We briefly review this research and then concentrate on the work being undertaken by the TRRL. On the experimental side, this work includes both full-scale and model tests to destruction; on the theoretical side, it involves both 'mechanism' and non-linear finite-element analyses.
