Title: Identification from the natural response of Vasco da Gama Bridge
Issue Date: 2004
Abstract: This paper describes the reanalysis of the ambient vibration data of Vasco da Gama cable-stayed bridge with thepurpose of testing the efficiency and accuracy of two recent and promising identification methods in a largeapplication: the Frequency Domain Decomposition (FDD) and the Stochastic Subspace Identification (SSI)methods. The modal estimates obtained using these alternative approaches are compared, taking also intoaccount the estimates previously obtained with the conventional Peak Picking technique from the free vibrationtest of the bridge, performed at the end of construction.
