TY  - JOUR
AB  - A significant number of old masonry bridges are still in use and need to be assessed  considering  current  traffic  loading  and  safety  requirements. Masonry  bridges are   complex   heterogeneous   systems,   where   masonry   arches   represent   the   main components.  Thus  arealistic modellingof  archesis  vital  for  accurate  assessment  of masonry  bridges.  The  authors  have  previously  proposed and  validated a  detailed mesoscale description for masonry arches allowing for the actual masonry bond and the specific  arch  geometry  including  the  case  of  skew  arches.In  this  paper,the  proposed mesoscalemodelling strategy is used in a comprehensive numericalstudyto investigate the effects of various parameters,includingmasonry bond and defects in the brickwork, abutment  stiffness  and  movements  at  the  supports,which  are  usually  disregarded  in practical  assessment  of  masonry  arches  and  bridges.The  results  achieved  show  how these  parameters  affect  the  ultimate  load  capacity,  failure  mechanisms  and  initial stiffness  of  square  and  skew  arches,  where  the  used  of  detailed  3D  mesoscale modelling  is  critical  in  providing  accurate  response  predictionsunder a  variety  of loading conditions for which reduced models might provide incorrect results.
