This paper presents results of the dynamic monitoring of a 10-storey r.c. tower in central Italy, focusing on the effects of ambient conditions. The installed monitoring system consists of a set of three accelerometers located on the last floor of the tower, including a velocimeter located at the foundation level and an acquisition software that, through a specifically developed algorithm based on operational modal analysis techniques, automatically extracts the modal parameters of the building from the accelerometric recordings. Ambient registrations derive from a weather station installed on the roof of the tower. Effects of the ambient parameters on the dynamic properties of the building are presented and discussed. Moreover, the building response to low intensity seismic events registered during the monitoring period is compared with that obtained from a calibrated numerical model by applying at the base the input registered by the velocimeter.

Abstract
This paper presents results of the dynamic monitoring of a 10-storey r.c. tower in central Italy, focusing on the effects of ambient conditions. The installed monitoring system consists of a set of three accelerometers located on the last floor of the tower, including a velocimeter located at the foundation level and an acquisition software that, through a specifically developed algorithm based on operational modal analysis techniques, automatically extracts the modal parameters of the building from the accelerometric recordings. Ambient registrations derive from a weather station installed on the roof of the tower. Effects of the ambient parameters on the dynamic properties of the building are presented and discussed. Moreover, the building response to low intensity seismic events registered during the monitoring period is compared with that obtained from a calibrated numerical model by applying at the base the input registered by the velocimeter.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
