摘要
This paper aims to investigate the various response characteristics of “rain-wind induced vibration” of cables and its fundamental mechanism. A series of wind tunnel tests has indicated that rain-wind induced vibration of cables can be classified into three types, that is a “galloping” type, which includes both divergent galloping and velocity restricted galloping, related to a negative slope of the lift force caused by an “upper water rivulet” and/or “axial flow”, the vortex-shedding type with long period, and their mixed type. In particular, this velocity-restricted response caused by vortex-shedding is excited by the three-dimensionality of conventional Karman vortex shedding along the cable axis.
