Valutazione e riduzione della vulnerabilità sismica di edifici murari storici in aggregato

The research is finalised to assess the seismic vulnerability of the aggregate and later on to suggest the mitigation criteria. The used methodology started collecting information on the structural relationship among buildings as well as on constructive techniques of each building. Historical events as well as the evolution and transformation of the buildings and the block were reconstructed in order to underline the items which could be correlated to the structural response in presence of seismic action both as improvement and weakening.
