Abstract

Three cable-stayed bridges are idealized by discrete analytical models in which friction force developed at movable supports is modeled by the Coulomb friction. Damping characteristics are determined by computed decay of free oscillation developed by smooth release from the original deformation specified. It is found from the analyses that damping ratio of cable-stayed bridges associated with energy dissipation at movable supports depends on mode shapes. Therefore, damping characteristics of cable-stayed bridge should be carefully evaluated considering mode shape.
