The heterogeneous nature of masonry coupled to its periodic stacking of quasi-brittle constituents leads to preferential damage patterns. Their influence can be incorporated in structural computations using computational homogenisation concepts. The ingredients needed to couple the structural and constituents scales are introduced for the case of damaging materials, and a coupled two-scale framework for masonry shells is outlined. This procedure allows incorporating naturally the anisotropic damaging effects of the masonry material degradation. The contribution will illustrate the two-scale results by comparing them to full fine scale models for in-plane failure and out-of-plane failure.
