On the influence of the aggregate condition on the vibration period of masonry buildings: A case study in the district of Naples

The present paper deals with the seismic investigation of a masonry building aggregate within the city of Bacoli (district of Naples) through quick and mechanical analyses with the initial target of evaluating the vibration periods of the individual Structural Units (S.U.) constituting the compound. In conclusion the comparison in terms of seismic vulnerability indexes between S.U. included in the aggregate, distinguishing the position (head or intermediate) in the compound, and the same S.U. considered as isolated constructions has been done.
