ARMAV analysis of Queensborough bridge ambient data

摘要: In this paper ARMY (Auto Regressive Moving Average Vector) models are used for system identification and modal analysis of o real bridge, the Queensborough Bridge over Fraser River in Vancouver. Canada. All collected analysed data due to ambient excitation, i.e. traftic. wind, etc. case excitation cannot be meawred, hence it’s necessary use which only need respclme perform t h e StruCture pmameters identification. The reports some results obtained with d@erent records. corresponding various environmental conditions.
