Damping Identification of Bridges Under Nonstationary Ambient Vibration

Sunjoong Kim, Ho-Kyung Kim

Engineering 2017, Volume 3, Issue 6, Pages 839-844 doi: 10.1016/j.eng.2017.11.002

Abstract:

This research focuses on identifying the damping ratio of bridges using nonstationary ambient vibrationHowever, most bridges are generally subjected to nonstationary excitations while in service, and thisamplitude-modulating function was calculated from measured responses to eliminate global trends caused by nonstationarydamping estimates, a comparative analysis was performed between an extracted stationary process and nonstationary
