The role of first line of defence against earthquake played by masonry infill panels has been recognised by many researchers. Provision for increasing the ductility and the energy dissipation capacity of masonry infill panels are under study in the framework of a currently active research programme, funded by the European Commission. The problem has been focused on the possibility of confining the panels by using polymeric grids. The effectiveness of this solution was investigated by performing tests on differing patterns of infills. The effectiveness of the adoption of the proposed methodology has been studied at the European Laboratory for Structural Assessment (ELSA). Two infill layouts with dimensions of 4.6m x 2.6m, one without openings, the other with non-symmetrical openings (a door and a window) have been analysed. In the paper the results of full-scale in plane cyclic tests on panels confined with the grids are compared with the behaviour of the panels in the same configuration, but constructed by using the conventional technique. The comparison between the response of the different panels seems to demonstrate that the energy dissipation capacity of infills can be strongly increased by confining the walls by means of the polymeric grids.
