Controlling excessive vibrations of stay cables on cable-stayed bridges is important to minimize the fatigue failure and damage at the cable anchorages. Using cross-ties to connect a vulnerable cable with its neighbors to form a cable network and installing external damper to a cable have been widely used in field. More recently, the idea of adding damper to an existing network to form a hybrid system was also proposed. Though the stiffening effect of the cross-tie solution are widely studied by numerous researchers, the damping property of a network has rarely been investigated. Also, the available studies on the hybrid system are very limited. In the present work, experimental study was carried out to investigate the modal behavior of a c...
