This article aims to emphasize the deformation state of a masonry wall, for four situations of masonry reinforcementwith polymeric grids. Polymeric grids are referred as seismic reinforcement solutions in the following masonry codes:Eurocode 8, and Romanian codes P100 and CR6. Polymeric grids can be used for confinement and reinforcement ofmasonry with bricks and mortar due to the properties of grids and mortar, and due to the cooperation betweenreinforcement and mortar that is anchorage.The masonry is an elasto-plastic material, to which characteristic curve σ-ε strain-deformation has a characteristicaspect. Deformation energy is represented by the surface determined between the σ-ε curve and the axis ε.The total specific deformation ε corresponding to a compression stress σ can be decomposed in two parts, one elasticεe, which is cancelled after the removal of external action, and the other plastic, remanent, εp.The case study present a comparative dynamic analysis of deformations state in structural masonry panels (softdiaphragms) in the following situations: plain, reinforce , confined and reinforced+confined masonry with polymer grids.
