A bidirectional test set-up based on a self-equilibrated airbag system was developed and used on three similarmasonry walls under distinct conditions: original, retrofitted, and strengthened. The results obtained and the main advantages and shortcomings found in the test set-up are discussed. Finally, some of the most popular retrofitting and/or strengthening techniques applied during the 1998 Azores reconstruction process are critically analyzed, aiming at suggesting quantifications for future interventions on existing unreinforced masonry buildings.engStone Masonryin situ TestSeismic BehaviorOut-of-PlaneStrengtheningIn situ Out-of-Plane Cyclic Testing of Original and Strengthened Traditional Stone Masonry Walls Using Airbagsjournal articlehttp://dx.doi.org/10.1080/13632469.2015.1107662
