AB  - Masonry vaults are present in a large number of historical structures and often used as floor-ing and roofing systems in monumental palaces and religious buildings, typically incorporat-ing no backfill. Many of these structures are located in seismic regions and have been shownto  be  particularly  vulnerable  during  recent  earthquakes,  with  a  need  for  accurate  modelling  to avoid future losses. Masonry vaults are often analysed using limit analysis procedures un-der  the  hypotheses  of  no-tension  material  and  absence  of  sliding  along  the  masonry  joints.However, this method can be inaccurate for barrel vaults found in buildings, which are typi-cally  slender  with  no  backfill.  In  this  case,  the  masonry  tensile  strength  and  the  progressive  damage propagation play an important role in the nonlinear behaviour and ultimate strength of the vault. In this study, a detailed mesoscale finite element mesoscale approach is used to model slender  unreinforced  barrel  vaults subjected  to  cyclic  quasi-static  and  dynamic  load-ing. According to this approach, 3D solid elements connected by 2D damage-plasticity inter-faces are used to represent the arrangement of bricks and mortar present in the masonry. Theproposed numerical description is first validated against the results from physical tests on a barrel vault under quasi-static cyclic loading. Subsequently, the shear response of a prototype vault  is  analysed  by  performing  nonlinear  simulations under prescribed horizontal displace-ments at  the  supports, considering  also  the influence  of  previous  damage  induced  by earth-quakes with different magnitudes.
