WIND INDUCED VIBRATION OF STAY CABLES

Cable-stayed bridges have become the form of choice over the past several decades for bridges in the medium to long span range. In some cases serviceability problems involving large amplitude vibrations of stay cables under certain wind and rain conditions have been observed. 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.
