The seismic performance of stone masonry buildings in Faial island and the relevance of implementing effective seismic strengthening policies

Additionally, a set of traditional retrofitting solutions were implemented to the original models in order to analyse and compare their influence over the building's global seismic performance. These solutions were adopted in the aftermath of the 1980 and 1998 Azores earthquakes by different design offices and engineering consultants, based on the designing recommendations specifically prepared by the Regional Laboratory of Civil Engineering (LREC) under the scope of the Faial rehabilitation process. Finally, fragility curves were derived based on the spectral response approach, and the results were critically discussed.
