Abstract
It is well known that damping characteristics are one of the most significant factors for aerodynamic stability of bridge structures, but few investigations have been made mostly due to lack of data.
In this study, coulomb friction force at movable supports is considered among various damping factors in order to get some informations for the damping characteristics of bridge structures. The numerical analyses based on the complex eigenvalue calculations are performed for several bridge models, paying attention to structural design factors. From these calculation results, some useful informations for the damping characteristics of bridge structures at movable supports are obtained.
