Abstract
The correct estimation of structural damping in wind engineering and structural dynamics in general is a very important and challenging issue, also due to the lack of available measurements and the uncertainty of the results. This paper reports the results of an on-site experimental campaign on a 390-m-main-span cable-stayed bridge with a steel-concrete composite deck, during the last erection stage. Damping was measured for the deck, pylon and stays, always monitoring the wind characteristics. A statistical analysis of the data was also performed.
