000022395 520__ $$2eng$$aThe stability of masonry arches plays a crucial role in the seismic assessment of historic and monumental buildings. The block-joint FEM model represents a major step forward with respect to the traditional rigid-brittle approach, allowing the assessment of the in-plane and out-of-plane arch behaviour and modelling of spatial systems such as cross vaults. Recent improvements of the method, among which the blocks modelled as curved frame elements and the pursuit of a static admissible configuration at the first step of the pushover analysis, are introduced. Moreover, the simpler block-block model that captures the behaviour of the arch through a lower number of finite elements is presented. The effects of passive and active strengthening measures such as CFRP sheets or prestress state are also considered in the models.
