Homogenization of periodic masonry : 2D (plane stress) or 3D modelling of the basic cell?Funded under: JRC-RELISTRU C
Through the homogenisation theory for periodic media, the global behaviour of masonry may be derived from the behaviour of its constitutive materials (brick and mortar). In particular, plane stress states have often been assumed at the microscopic level, on account of the relatively small thickness of masonry walls. In order to determine the range of validity of such an assumption, the homogenisation theory is implemented in a rigorous way on a two-dimensional representative basic cell and on a three-dimensional one, both brick and mortar being subjected to isotropic damage. It is shown that, in the elastic range, 2D and 3D computations give very close values for the macroscopic elastic constants. In the non-linear range however, 2D computations may lead to erroneous results in the value of the ultimate load and in the mode of failure.
