The homogenisation theory for periodic media is used to derive the in-plane macroscopic non-linear behaviour of masonry. Two different assumptions are envisaged: plane stress and generalised plane strain. Assuming a continuum damage modelling for the brick and the mortar, the two-dimensional boundary value problem associated with the homogenisation method is presented, together with the numerical strategies able to solve it. Emphasis is on the numerical difficulties related to the softening character of the constitutive law. The results obtained for typical loading paths are presented. Contrary to common sense, the effect of the head joints is substantial and only the generalised plane strain assumption leads to realistic results.
