Abstract
This paper deals with a newly developed damper, called a keel damper, used to reduce bridge vibration caused by wind or vehicles passing over it. The keel damper consists of a combination of steel plates and damping resin, and is attached to the girder edge of the bridge. It can provide high damping performance for the bridge vibration in spite of the simple structure. In this paper, the basic structure of this damper is introduced. In addition, a scale model and numerical analysis results for a model bridge are also discussed.
