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 pre-dictions 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 de-composition). 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 pre-dictions 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 de-composition). 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
