摘要：Hezhang Large-span Bridge is a concrete continuous rigid frame bridge with super high pier. The highest pier reaches 197m and stands the peak among the similar bridges. In order to study the wind resistance capacity of the bridge, ANSYS, a finite element software, is applied to establish models at the stage of the largest cantilever constructing and completing of the bridge. The dynamic characteristics of the models are solved by subspace iteration method and the fluctuating wind velocity time history was generated by modified Fourier spectrum method. After that, the buffeting load time history is calculated based on the theory of quasi-steady state and the buffeting time history of the stage of the largest cantilever constructing and completing of the bridge is gained respectively by time history analysis.
