Resumo (PT): The present work aims at characterizing and evaluating the out-of-plane seismic performance of stone masonry walls through field experimental tests and their behaviour improvement resorting to strengthening methods. In this line, several in-situ experimental tests were carried out using an innovative technique to mobilize walls of existing constructions damaged by the Azores 9th July 1998 earthquake. It is worth mentioning that strengthening techniques as used during the reconstruction process were also applied to the previous tested walls in order to improve their seismic resistance, thus providing a means of assessing the seismic adequacy of those techniques. Finally, a full comparison is presented concerning the different applied techniques and the seismic performance improvement when compared to URM constructions, taking into account maximum strength, displacement capacity and energy dissipation, among other issues.
