This study is to investigate the effects of environmental and operational conditions on the dynamic behaviour of bridge structures. A long-term monitoring system has been installed on a cable-stayed bridge and there are 24 accelerometers on bridge deck. Monitoring data from two typical days have been analysed and the modal analysis is also carried out to extract modal parameters. Effects of changes in environmental and operational conditions, such as temperature and traffic, on structural dynamic properties are discussed.
