Abstract: The stay cables in cable-stayed bridges are prone to exhibiting oscillation of large amplitude due to their large flexibility, small mass, and small damping. Continued oscillation of the cables may seriously influence the safety and durability of cable-stayed bridges. Apart from the rain- wind-induced cable vibration, large-amplitude oscillation of cables caused by parametric excitation due to support motion was recently observed in cable-stayed bridges. This kind of cable oscillation is produced by the deck and/or tower motion induced either by moving traffic or by buffeting response of gust wind. The oscillation mechanisms and control methods of stay cables excited by the deck and/or tower motion are less studied than the rain-wind-induced vibration. In this paper, a nonlinear dynamic model for the simulation and analysis of a kind of parametrically excited vibration of stay cables caused by support motion in cable- stayed bridges has been proposed.
