== Abstract ==

Unreinforced Masonry (URM) has been extensively used as a construction material
in mass structures with predominant compression load paths. Despite its reasonably
established performance under gravity actions, it can be quite vulnerable to seismic loading,
predominantly due to its limited tensile strength and associated quasi-brittle failure modes.
Therefore, a reliable seismic assessment of URM structures, including heritage buildings, is
vital to ensure life safety and minimise their risk of collapse. This can assist in implementing
effective remedial measures, if required, to ensure desirable performance level in future events.
Despite significant advancements in masonry research, practical assessment of URM has
always been a challenge for structural engineers due to the complexity of the mechanics and
geometry involved. Different modelling approaches have been trialled so far, which are
typically based on equivalent frame, discrete and continuum elements in 2D/3D domains. In this paper, a simplified nonlinear model is introduced within the framework of conventional layered shell elements, which can be easily implemented in commonly used FE packages, e.g. ETABS and SAP2000. In this model, the URM shell element comprises three layers accounting for cohesion and axial-frictional behaviour parallel and perpendicular to the bed joints, where the mechanical properties can be adjusted for various masonry configurations. The
performance of the proposed model is validated against several experimental tests available in
the literature, where a good correlation with test data is achieved across various design
scenarios and loading conditions.
