Abstract
This paper presents the reduction phenomenon of the added dam** in a stay cable caused by static wind loads acting on a cable with an external damper. First, an equation of motion of a sagging cable is derived that takes the consideration of dead loads including cable self-weight and static wind loads into account. Second, a finite difference formulation (FDF) for cable vibration is introduced to address the equation of motion and to determine the added cable dam**. Third, the impacts of cable bending stiffness, damper support stiffness and various types of boundary conditions at cable ends consisting of hinged, fixed and rotational restraint ends on cable vibration characteristics are investigated. The results showed that in the presence of static wind loads acting on a cable, the global stiffness of a cable increases, leading to an increase in vibration frequency and a decrease in the added cable dam**.
