Modélisation jusqu'à rupture de murs en maçonnerie chargés dans leur plan

ABSTRACT This paper deals with modeling of mechanical behaviour of masonry walls submitted to in-plane loading. The adopted strategy consists of modelling separately the appropriate local failure mechanisms of thoug elements and mortar joints. A particular attention is dedicated to brick crushing mechanisms which were captured with strong displacement discontinuities within the framework of incompatible mode method. A perfect plasticity model including di-latancy has been employed for the joints modeling. This model has been compared with two experimental results. We show that we are able to well reproduce the global behaviour of such structure (stiffness and peak load) and thus construct reliable predictive model of the masonry walls by using only the experimental characteristics of their components.
