Experimental vibrational analysis is used in the knowledge process of a historic building, made of confined masonry, a construction system suggested in the reconstruction after the 1915 earthquake at Avezzano, Italy. The building was the primary subject of the usual experimental campaign to verify the structural geometry, the characteristics of the materials and the permanent loads. Then, a detailed experimental vibration analysis was carried out. Data were analysed both in the frequency and in the time domains. This combined approach allowed us to point out the importance of the floor deformability on the dynamic behaviour of the structure. A finite element model was set up using the equivalent frame method and calibrated on the basis of the experimental vibrational analysis results. The constitutive law of the confined masonry was fine-tuned, following the literature and present standard suggestions. The pushover analyses allowed us to uncover the behaviour factor of the structure and the seismic safety index, which was found to be quite low and very similar to that obtained via a response spectrum analysis. |
