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

摘要

The performance of masonry walls reinforced using polymeric grid embedded into plaster layers as a tools for the seismic enhancement of brick masonry buildings has been investigated by experimental tests. The results of the experimental campaigns are summarised and discussed in the paper. Based on the experimental data and on the results of numerical simulations, simplified models to be used as tools for the design of the retrofitting intervention are proposed. The models properly consider the so called "first" and "second" collapse mechanisms as well as the grid effect in the evolution of the above mentioned mechanisms.
