Résumé
By homogenization, we propose a simpli ed 2-dimensional model for e ective behaviors of structures made of some thin at masonries where the mortar occupied a rather thin domain and is far softer than the bricks. Because a steady-state problem considered here may be formulated in terms of minimization, we use the method of variational convergence. Our model is simpler than the genuine one because it involves a homogeneous body and is accurate enough due to our convergence result. This work also shows what a reasonable candidate for e ective energy density of the assembly of bricks and mortar could be
