Abstract: This paper describes a wind tunnel test of segmental modes of a flexible suspension bridge with main span 360 m in static condition, including the entire process, Contents, current phonomena and test results, this paper also gives the curves of the coefficients of three components (lift, drag and torsional moment) under a constant wind force, and the influence of the stiffened girder shape, the wind penetration rate of the deck, pedestrian load and the influence of the tailing on tue wind resistance of the structure.
