Numerical models of masonry arch bridges are required for accurate determination
of ultimate failure loads. Finite element analysis (FEA) has been surprisingly under-
used in this area perhaps because the main features of masonry behaviour, namely
strongly non-linear loss of stiffness through cracking and failure of an arch by the
formation of a mechanism, are hard to model using conventional continuum
elements, familiar to industrial users. This paper describes models of masonry arch
bridges built within a basic FEA package, basing numerical results on field data
from tests to destruction on arch bridges.
Keywords: masonry arch bridges, finite element modelling, crack modelling
