An overview on seismic analysis of masonry building aggregates

Conservation of historical centres is a pressing need for Mediterranean countries, that are characterized by masonry aggregates representing the most typical construction type within cities. Masonry clustered buildings were usually designed without seismic design criteria. Moreover, current standard codes do not foresee clear calculation method to predict their non-linear behaviour. For this reason, in paper, wide overview on response has been done considering analysis at different levels, from simplified large-scale evaluations sophisticated analyses. In former investigation kind, vulnerability form appropriately conceived applied with aim perform risk both empirical approaches and real data deriving occurred past earthquakes. second evaluation type, macro-elements examined reference Italian territory. particular, global assessments, performed using 3Muri program, have final goal derive fragility curves structural units plan position building (end row, internal, corner).
