Model Tests to Study Rain/Wind-Induced Vibration of Stay Cables
Rain- and wind-induced vibration in the stay-cables of cable-stayed bridges is a problem that is generating greater attention as more of these bridges are constructed around the world. Large-amplitude stay-cable vibrations have been observed on existing bridges at low wind speeds of less than 30 mph with and without the presence of rain. This problem has challenged the very integrity of these aesthetically pleasing structures and is alarming to the passing motorist. Rain- and wind-induced vibration is an aerodynamic phenomenon that was relatively unknown during the design of many cable-stayed bridges, resulting in the need for vibration countermeasures. In this paper, various aspects of the rain and wind vibration phenomenon are presented based on a series of wind tunnel section model tests that were performed with a newly developed two-degrees-of-freedom elastic suspension system. The effectiveness of a vibration mitigation device was also examined.
