The main purpose of this paper is to propose an approach to define a finite element capable to describe adequately the behavior of some typologies of masonry walls which are characterized by a multiple leaf internal structure. This method is based on the homogenization theory of non-periodic material. Firstly, the peculiarities of the masonry walls are highlighted. Then, the proposed element takes into account the effective non periodic nature and the multilayered structure of the masonry walls. In particular the elastic moduli of the homogeneous material equivalent to the heterogeneous one are determined. The proposed approach can be used to study very large structures (monumental and historical buildings) in order to highlight their more stressed portions. An example illustrates the effectiveness of the proposed method.

Abstract
The main purpose of this paper is to propose an approach to define a finite element capable to describe adequately the behavior of some typologies of masonry walls which are characterized by a multiple leaf internal structure. This method is based on the homogenization theory of non-periodic material. Firstly, the peculiarities of the masonry walls are highlighted. Then, the proposed element takes into account the effective non periodic nature and the multilayered structure of the masonry walls. In particular the elastic moduli of the homogeneous material equivalent to the heterogeneous one are determined. The proposed approach can be used to study very large structures (monumental and historical buildings) in order to highlight their more stressed portions. An example illustrates the effectiveness of the proposed method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
