Abstract
An unexpected wind-induced vibration was observed on the Yi Sun-sin Bridge in October 26th, 2014. Since the bridge was aerodynamically well designed, the cause of the vibration was investigated via a series of two-dimensional wind tunnel tests as well as the system identification based on the field data. Since the primary source was estimated as the temporal screens applied on the bridge railings for maintaining curing temperature of the replaced wearing surface, wind tunnel tests were carried out for the section model of the deck section with and without the screens. This paper presents the screen effects on VIV of the investigated bridge and the illustration of the observed vibration based on in-depth investigation with a series of two-dimensional wind tunnel tests as well as the system identification based on the field data.
