Abstract:The gallery bridge is the special bridge structure with unique characteristics of Dong nationality of pavilion structures. In order to study the aerodynamic parameters and wind-vibration coefficients of pavilions on the gallery bridge, taking the Fenghuangling Bridge in Liuzhou as the research object, the virtual wind tunnel simulation technology is used to obtain the aerodynamic coefficients of each layer of pavilions on the gallery bridge, and analyze the changing law of aerodynamic coefficients. The wind load time history analysis is carried out on the finite element model of the gallery bridge, and the wind vibration coefficients of each layer of the pavilions and the changing law are obtained. The research results can provide a certain reference for the maintenance of the existing gallery bridges and the wind resistance design of gallery bridge structures.
