Abstract

Cable is one of the basic construction members of a cablestayed bridge. The wind loads on cables constitute a high proportion of total wind loads on the bridge, and the windinduced vibration is an important problem of great concern in bridge design. Through a selfdesigned vibration test system for staycables, the vibration model tests for a rigid staycables model with diameter of 120 mm as well as for 25 kinds models of staycables wound with helical lines were conducted in a wind tunnel.The changing rule of the vibration amplitude along with the Reynolds number was analyzed. The results show that winding a helical line on the cable can reduce the Reynolds number effects on it. When the helical line winding spacing is constant, the amplitude trends to decrease along with the increase of helical line diameter. When the helical line diameter is constant, the amplitude trends to decrease along with the decrease of helical line winding spacing. The vibration stability is improved with the increase of helical line diameter and the decrease of helical line winding spacing.
