✦ Synopsis
Through the homogenization theory for periodic media, the macroscopic behaviour of masonry may be derived from the behaviour of its constitutive materials (brick and mortar). Such a procedure has been used by many authors but always in an approximate manner. In particular, masonry has been considered either as in®nitely thin (two-dimensional media under plane stress), or as in®nitely thick (two-dimensional media under generalized plane strain). In order to determine the range of validity of either assumption, the homogenization theory is here implemented in a rigorous way, i.e. taking into account the ®nite thickness of masonry. Both brick and mortar being assumed as subjected to isotropic damage, numerical computations show that the above-mentioned assumptions have little in¯uence on the macroscopic elastic behaviour of masonry, but may signi®cantly aect its non-linear response (ultimate load and mode of failure). # 1997 by
