Book excerpt: This study was conducted in order to develop a set of consistent design guidelines for mitigation of excess cable vibration on cable-stay bridges. In order to accomplish this objective the Project Team started with a thorough review of existing literature to determine the state of knowledge and identify any gaps that must be filled in order to enable the formation of a consistent set of design recommendations. This review indicated that while the rain/wind problem is known in sufficient detail, galloping of dry inclined cables was the most critical wind-induced vibration mechanism in need of further experimental research. A series of wind-tunnel tests was performed to study this mechanism. Analytical and experimental research was performed to study mitigation methods, covering a range of linear and nonlinear dampers and cross-ties. The study also included brief studies on live load induced vibration and establishing driver/pedestrian comfort criteria. Based on the above, design guidelines for mitigation of wind-induced vibrations of stay cables were developed.
