Abstract: The wind response performance of Huanghe Park landscape footbridge in Suqian city is investigated via full bride aeroelastic model test in smooth and turbulent flows with 3 types attack angles. The wind velocity factor for height modification is compared between the theoretical values and those offered in specification, and the discrepancy reasons are analyzed. The research results reveal that the much rougher ground surface, the lower height, and the obvious difference for modification factor. The factor values agree well if it is higher than 40m. For Huanghe Park landscape footbridge, with 3 kinds of attack angles, no obvious vortex vibration can be observed, and the aerodynamic stability satisfies the requirements. The buffeting displacement standard deviation may be higher than the mean value, even for higher wind velocity. The displacement peak factors and their ratios in smooth and turbulent flows varies in the interval of [2.5,4] and [0.8, 1.2]. No explicit relations exist between peak factors and wind flows, wind velocities, wind attack angles. The investigations can offer valuable reference for rational determination of peak value in wind vibration theoretical analysis.
