Abstract
In recent years, wind-induced cable vibrations of cable-stayed bridge have been observed, and phenomena of these have become a major problem in wind engineering. This paper deals with the vibration control of stay cable by installation of two types of dampers. The authors have derived a practical estimation method for the modal damping in stay cable with dampers. Several examples demonstrating the application of the proposed method are also presented for the cable model with the length of 100m and 250m. From these results, some useful informations for the vibration control of stay cable by installation of two types of dampers are obtained.
