| 1 | Dynamic Characteristics of a Curved Cable-stayed Bridge:Operational Modal Testing and FE Modeling显示文摘This paper summarizes the analytical and experimental dynamic analyses carried out to assess the actual dynamic behaviour of a curved cable-stayed bridge,recently erected in the commercial harbour of Porto Marghera ( Venice,Italy). Ambient vibration tests were carried out to determine the dynamic characteristics of the bridge and more than 20 modes were identified in the frequency range 0~10Hz. In the theoretical study,a 3D FE model of the bridge was developed using an integrated CAD-FEA approach; subsequently,the information obtained from the field tests,combined with simple manual tuning,provided a linear elastic model,accurately fitting the modal parameters of the bridge in its present condition. | Bruno Briseghella Fulvio Busatta Carmelo Gentile Enzo Siviero Tobia Zordan | 2010 | 施工技术2010，39，5： | 1 |
