POLYMERIC GRID FOR A COST EFFECTIVE ENHANCEMENT OF THE SEISMIC PERFORMANCE OF MASONRY BUILDINGS

The performance of masonry walls reinforced using p olymeric grid embedded into plaster layers a s a tools for the seismic enhancement of brick masonry buildings has been investigated by experimental tests. The re sults of the experimental campaigns are summarised and discu ssed in the paper. Based on the experimental data a nd on the results of numerical simulations , implified models to be used as tools for the des ign of the retrofitting intervention are proposed. The models properly cons ider the so called “first” and “second” collapse mechanisms as well as the grid effect in the evolut ion of the above mentioned mechanisms.
