RISK ASSESSMENT OF CAMERINO MUNICIPALITY: A CASE STUDY OF VALLICELLE DISTRICT

This paper applies the Performance-Base Earthquake Engineering (PBEE) framework to estimate the risk of a urban district recently hit by a earthquake, in order to compare model prediction with effective damage observed after the event. For this purpose, the reinforced concrete buildings of the Vallicelle district of Camerino, are considered. This district consists of different typologies of structures (Low, Middle and High rise) built at different times conforming to different seismic codes. After the “Central Italy 2016” earthquake, a detailed survey of damage was carried out, as well as studies about the seismic hazard of this area, subjected to seismic wave amplification. In the PBEE framework, the seismic response of the structures is described by means of fragility curves proposed in literature according with the typologies of buildings present in the area and a loss analysis in terms of expected annual losses is carried out. Finally, a comparison with the observed damage experienced after the seismic sequence is provided.
