Damping Performance of Two-Cable Hybrid System Equipped with Both Viscous Damper and HDR Damper
Publisher: ASCE
Abstract: In cable-stayed bridges, a cross-tie solution is considered an effective measure to enhance the in-plane stiffness of main cables while the damping increment of main cables is achieved by installing dampers on the main ...
Influence of Negative Stiffness Damper on Stay Cable with Neoprene Rubber Bushings
Publisher: ASCE
Abstract: Stay cables on cable-stayed bridges are inherently low-damped flexible structural members. In order to improve their energy-dissipating capacities, external dampers are installed to control undesired cable vibrations. ...
Impact of Key System Parameters on the In-Plane Dynamic Response of a Cable Network
Publisher: American Society of Civil Engineers
Abstract: Using crossties to connect a cable which has experienced or is prone to violent motions with its neighbors and form a cable network has been successfully applied to a number of cable-stayed bridges to control stay cable ...
Analytical Investigation of Performance of Passive Negative Stiffness Damper in Two-Cable Hybrid Network
Publisher: American Society of Civil Engineers
Abstract: Stay cables in cable-stayed bridges are susceptible to vibrations due to their inherent flexibility and low damping. Different countermeasures to control such vibrations have been extensively researched as well as implemented ...
