Aggregated buildings, masonry, seismic damage, capacity curve, damage probability matricesAbstract
In this work a study about the seismic behaviour of a set of masonry aggregates buildings located in the city of Barcelona, Spain, is presented. Considering the age of these buildings (more than 70 years) two mechanical properties for the masonry were defined. The seismic action considered is defined by elastic response spectrum defined by Eurocode 8 for the seismic acceleration of Barcelona. To analyze these buildings the capacity spectrum method was used, from which the capacity curve and the fragility curves are obtained for evaluating the seismic expected damage. Damage probability matrices quantified the seismic damage and they are obtained from the fragility curves and the performance point. Considering that the city of Barcelona is located in an area of low seismicity, the results show an important seismic damage.
