The paper deals the proposal of a constitutive model for the Finite Element Method (FEM) nonlinear analysis of masonry structures and the use of nonlinear static procedure in order to estimate the seismic performance of masonry buildings. In particular, the mechanical behaviour of masonry was simulated as a continuum homogeneous and isotropic material, us-ing the concrete smeared-crack model modified by means of an interaction with the plasticity Drucker Prager domain and by means of the definition of a new compression failure surface. The calibration and validation of the FEM model was carried out by means of sensibility analysis of different mechanical parameters, based on experimental data available in literature. Finally the proposed material constitutive model was used for the seismic performance assessment of a typical example of masonry buildings.

Abstract
The paper deals the proposal of a constitutive model for the Finite Element Method (FEM) nonlinear analysis of masonry structures and the use of nonlinear static procedure in order to estimate the seismic performance of masonry buildings. In particular, the mechanical behaviour of masonry was simulated as a continuum homogeneous and isotropic material, us-ing the concrete smeared-crack model modified by means of an interaction with the plasticity Drucker Prager domain and by means of the definition of a new compression failure surface. The calibration and validation of the FEM model was carried out by means of sensibility analysis of different mechanical parameters, based on experimental data available in literature. Finally the proposed material constitutive model was used for the seismic performance assessment of a typical example of masonry buildings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
