A non-linear 3D finite element model for the ‘microscopic’ analysis of masonry structures subjected to static and seismic loads is presented in this study. The model considers masonry as a two-phase material, treating bricks and mortar joints separately, thus allowing for non-linear deformation characteristics and progressive local failure of both bricks and mortar joints. The influence of the mortar joints is taken into account by using ‘interface’ elements to simulate the time-dependent sliding and separation along the interfaces. Analytical and experimental solutions available in the literature have been employed to verify the results obtained from the present finite element model, showing that it is capable of a high degree of accuracy.
