Panneaux en maçonnerie renforcés à l'aide de matériaux composites : approche de type calcul à la rupture et étude expérimentale

Abstract : Maintenance, repair and reinforcing of masonry walls with composite materials glued require the development of methods and techniques for evaluating the suitability for service and retraining for both their functional restoration for their adaptation to new constraints (changes seismic zoning for example). This thesis aims to propose an evaluation tool by calculating the limit state of masonry walls,reinforced bonded composite, loaded in their plane.The work done on modeling by homogenization of masonry walls and acampaign experimental characterization of charge transfer between a reinforcement of carbon fiber fabric and a backing of hollow blocks concrete by means of an adhesive joint. To model the resistance of masonry walls, we propose a law for elastic perfectly plastic behavior in the plane formed of masonry blocks connected by mortar joints. The convex plasticity is obtained byperiodic homogenization technique which takes into account the three dimensional nature of the basic cell. This gives a convex bounded by several surfaces of charge. An algorithm digital original is then proposed and programmed in the finite element software ABAQUS. Numerical simulations using the developed module are presented
