Abstract
An energy-based evaluation method of vibration damping in cable-stayed bridges is proposed and discussed in this paper. The damping values of five modes of the Tsurumi Tsubasa Bridge, which were obtained by the field vibration test, are analyzed by using the energy method. It was found that the contribution of dissipation energy from shoe friction, aerodynamic damping, and oil dampers and high damping rubbers for suppressing cable vibrations, can be large in the Tsurumi Tsubasa Bridge. In addition, damping characteristics of this bridge, such as high damping value and mode dependency of damping were reasonably explained by the results of energy analysis.
