Structure and architecture in the seismic area
The attention towards the seismic risk has crossed, as a sort of permanent memory, the culture of peoples, resulting in a constant effort in the search for concrete solutions capable of guaranteeing a sufficient degree of safety in buildings whose vulnerability depends on the construction and construction characteristics and the quality of the materials used; as experienced by the analysis of the behavior of historical architectures during the seismic events that aff ected Central Italy in 1979, 1997 and 2016: the damaged buildings showed obvious construction defects, while they remained undamaged or aff ected by minor damage entities well built ones. The appropriate risk mitigation actions can be identified through geoseismic engineering studies but at the same time it is necessary to investigate the local seismic culture expressed in the constructive characteristics of the historic buildings and to introduce forms of intervention and articulated measures in relation to the assessment of the actual forms of vulnerability, accentuating the residual resources, without performing any replacement either in the material consistency or in its own structural functionality.
