In this paper, we introduce a phenomenological model approximating the behaviour of masonry structures, which is based on a lowtension elasticbrittle eb assumption with evolutionary tensile behaviour. The eb model is conceived by embedding a decaying tensile strength in the material behaviour, and it is able to achieve good agreement with the real behaviour of masonry. It is computed as the average of coordinates of the adjacent nodes, where weighted edges are considered as multiedges collapsed into one.
