TY  - JOUR
AB  - Masonry arch bridges often include multiple spans, where adjacent arches and piers interact with each other giving rise to a complex response under traffic loading. Thus, the assumption commonly used in practical assessment that multi-span masonry viaducts behave as a  series  of  independent single-span  structures,  may  not  be  realistic  for  many  configurations. While several experimental and numerical studies have been conducted to investigate single-span masonry arches and bridges,only limited research has been devoted to the analysis of the response  of multi-span masonry  bridges. This  study  investigates  numerically masonry  arch bridges with multiple spans subjected to vertical loading. For this purpose, an advanced finite element description,which is based upon a mesoscale representation for masonry and accounts for both  material  and  geometric  nonlinearities, is employed  to  shed  some  light  on  the actual behaviour of these structural systems. A validation study is first carried out to confirm that the adopted modelling strategy is  capable  to accurately simulate previous experimental results.Then, the  influence  of  some  critical geometrical and  mechanical parameters  that  affect  the bridge response is evaluated  through a parametric  study.The  effects of  pier  settlements and brickwork  defects are  also  investigated,  as  well  as the  interaction  between  adjacent  spans through comparisons against the response of single-span counterparts.
