Seismic vulnerability of existing buildings: non-invasive approach for dynamic behaviour assessment

This paper presents a brief overview of the concept of seismic risk, with particular regard to existing civil buildings. Given that the seismic risk can be expressed as a combination involving seismic hazard and seismic vulnerability, these aspects are both discussed, describing the factors that le...
