A multiscale model for the structural analysis of the in-plane response of periodic masonry panels is presented, adopting at the macroscopic level the Cosserat micropolar continuum. At the microscopic scale, the classical Cauchy model is employed and a plastic-damage constitutive law is introduced. The nonlinear homogenization is performed employing the Transformation Field Analysis (TFA) technique. A numerical procedure is developed and implemented in a Finite Element (FE) code in order to analyze masonry structural problems.
