The structural identification from environmental vibration testing of a hospital building in Avezzano (Abruzzo - Italy) was presented. The comparison of the results enables to verify and calibrate numerical predictions on the base of data obtained from modal testing. The response of the structure in the time domain was recorded by highly sensitive sensor network, integrated by a data acquisition system. The identification was performed using techniques of modal extraction in the frequency domain (frequency domain decomposition). During the calibration process of the numerical model the values initially adopted were successively corrected in order to identify a reliable structural model to be used to have an accurate seismic vulnerability assessment of the hospital building

Abstract
The structural identification from environmental vibration testing of a hospital building in Avezzano (Abruzzo - Italy) was presented. The comparison of the results enables to verify and calibrate numerical predictions on the base of data obtained from modal testing. The response of the structure in the time domain was recorded by highly sensitive sensor network, integrated by a data acquisition system. The identification was performed using techniques of modal extraction in the frequency domain (frequency domain decomposition). During the calibration process of the numerical model the values initially adopted were successively corrected in order to identify a reliable structural model to be used to have an accurate seismic vulnerability assessment of the hospital buildingI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
